Apple has really confused people with this whole thing. I think
we'll be answering this question for about the next year or so. There is
no "option" to get an FPU on a C650. What you have is a choice of CPUs:
there is the 68LC040 that does not have an integrated FPU like the full
'040 and is only present in the base 4/80 model of the C650 .
And there is the full '040 which you get when you order anything other
than the base 4/80 configuration. Therefore, since you have ordered one
of the 8MB versions with on-board Ethernet models you will not be
getting the LC040. But even if you wanted to have the LC040 you wouldn't
be able to order a C650 with 8MB RAM, on-board Ethernet and an LC040.
It's not an "option."
Also, a note to people out there that have 4/80 C650s and C610s
thinking that there is an optional FPU, the '040 class chip cannot
recognize an external FPU, so there is no socket on the motherboard for
a FPU chip and you cannot go out and purchase an FPU on a PDS card or
something like that. The only way to get an FPU in these machines is to
replace the LC040 with a full '040. And if you have a C610, you will not
need to worry about a heat sink if you do replace the LC040 with the
full '040, but if you have a 4/80 C650 you do need to have a heat sink.

I have the a CD-Technology drive with the Toshiba mechanism, and it is
supposedly the fast and best now. It has an access of 200ms and a data
transfer rate 300Kb/sec. It is multisession photo-cd compatible. It is
available from educorp for $599, the CD-Technology one, and comes with two
mail in coupons for two free CDs. I'm not sure if the cd's are good, since
I've only had the drive a little less than a month and had the cd's shipped
to my home address in california instead of here in maryland. The
CD-technology drive has a separate power supply separated from the drive,
which supposedly gives it a longer life, and keeps it cleaner with no fan to
attract dust. A Toshiba brand drive is also available, but I think the
CD-Technology is better, since you get the same mechanism, and at a slightly
lower price with two free CDs.
The Apple 300/330i Drive, Sony Mechanism, is around a 300ms access time I
think, and a data transfer rate of 300Kb/sec. I know it is the slowest of the
three mentioned here. It is not widely available, except through the apple
catalog, which is bad at a price of only $599. It is also multi-session photo
cd compatible. I think the external model comes with 7 free cds, some of
which are pretty good.
The NEC drive has been out the longest. it has an access time of 280ms and
a data transfer rate of 300Kb/sec. it is available from many vendors around
$600 dollars, including Educorp. It wasn't multi-sesssion photo-cd compatible
before, but I hear that the current version that is shipping is. Owners of
the older drives can get an upgrade. It does not come with any free cd's
unless you buy it in a bundle.
Of the three CD-Rom drives above, i think the best choices would be the
Apple drive and the CD-technology drive. The apple drive for it's
compatibility with apple products and the cd-technology for it's
speed and performance.
BTW, the models of the drives are:
Apple: AppleCD 300 or AppleCD 300i
CD-Technology: CD-T3401
NEC: CDR-74
I'm very happy with my drive. And have had no compatibility problems
whatsoever. If I am wrong about any of the above, do correct me, but I am
pretty sure of myself, even when I think I'm not.
Also, some of you out there might notice that I have the same last name as
the president of CD-Technology which happens to be in southern california,
my hometown. However, I AM NOT a relative nor do I know the guy. Liu is
just a common chinese name, especially in southern california, with the
enormous chinese community. Besides, one of my doctors in california has
three Steve Liu's as patients and another Steve Liu comes to my school and
lives in the next dorm. This is to show that Liu is very common.

I think you must be talking about the Syquest 105 .
It is a 3.5" Winchester technology drive pretty much like the other Syquest
drives in terms of how it works. According to the latest MacLeak, the
drive has a 14.5 ms access time, 1.9 MB/s sustained throughput . The drive was originally released for the PC
and just recently was released for the Mac world and through they are currently in limited supply, according
to a Syquest rep. they are in the process of ramping up for mass production.
I have already seen them advertised by a number of manufacturers in MacLeak
including PLI, MassMicro, ClubMac, and MacWarehouse's PowerUser. The PLI
and MassMicro units are priced at just around $1000; the lesser name brands
are going for around $750 for an external drive. Cartridges which hold
105 MB sell for about $80 each. At these prices, the drives and cartridges
are cheaper and better performing than the 88MB drives.
Cost per megabyte compares favorably with other cartridge drives and Bernoulli
drives, but for large amounts of data optical is still cheaper, and more
reliable. Personally, I'm excited by the new drive and look forward to
getting my hands on one.

This problem is most likely the same that all cx users are experiencing....
Thanks to one very adventurous USENET reader it is easily fixed, if it is the same problem......
Best I can figure it is due to time, heat and repeated warmup/cool downs in
the power supply....i.e., bad solder joints in the power supply circuit
card. Go get a desolder tool from radio shack, a low wattage iron and some
good nonacid solder and resolder the lower left quadrant of the circuit
card with the AC plugs facing away from you..........or get someone to do
it for you. It took me less then 10 minutes and saved me at least $300 for
a new supply!

I don't know how to say it best but you are gaurenteed that the
price of the C650 is going to drop this year. This week's MacWeek
reports that Apple is probably planning a drop in August. My guess
is that it may come sooner if Apple decides to change the price
structure upon release of the multimedia units this summer.
Your price looks pretty good at about $50 more then I payed for
mine last month. I would have rather waited for one of the new
machines this sommer but the resale value of my
IIci would have not been squat by then. Thus, financing forced me
to purchase now. I'm happy with the machine and won't feel
betrayed at all when Apple cuts the price to less then $1000 next
week .
Bottome line: If the C650 does what you want, buy it. If you wait
until the Cylcones come out for a price break then you might as
well wait for the PowerPCs to come out for another price break and
then the units which follow them. You may save some money but
you've lost a lot of time when you could have been using the
computer. Face it, Apple's prices are going to be in a continuous
state of flux. At least they aren't going to try raising them
again .

To display Millions of colors on a 16" monitor you need 2MB of VRAM

Correct. This is the amount of on-board VRAM that the Q800 comes
with.

Yes this is possible. Technically, you only need to take out 2 of
the VRAM SIMMs but leaving in the other two will not get you anything
because the 950 cannot really do anything with 1.5MB of VRAM. It only
knows 1MB and 2MB.
>From the documentation I have, the Quadra 800 must get 1 Mo VRAM to have
>16-bit color, is that correct?
Yes, this is correct. You get to 1MB by putting 2 256k VRAM SIMMs
into the VRAM SIMM slots on the Q800's motherboard.
>Bonus question: where do VRAM SIMMs hide? From the 950 documentation, they

Yup. You have to take off the power supply. It's only a couple of

The problem mentioned last is a known Quadra SCSI problem, it was heavily
discussed last year and an Apple employee pointed out that there was a
one byte error in the SCSI driver routine for the Quadra's . System 7.1 should not have that problem, for most people the
solution was to get an updated driver from the drive manufactor. In my
case MASS Microsystems wrote a new driver which fixed the problem on my
Quadra
700, all that occured early last year.

We have recently obtained a Centris 610 and it has developed an unusual

Model: 610 with 8 MB/230 HD, 512K VRAM, no cards
Monitor: Apple 16"
When the computer is set for 256 colors and certain operations are done,
particularly vertical scrolling through a window, horizontal white lines
appear on the monitor . These lines accummulate as the operation is continued. If a
window is moved over the involved area of the screen and then moved away
the line disappear from that area of the screen. This problem is not
observed if the monitor is configured for 16 colors or a 14 inch Apple
monitor with 256 colors is used.
I suspect a bad video RAM chip but cannot be certain. The problem has

Yes, but if you upgrade the VRAM in a 900 you get 24 bit color. So
you really don't care. My point is that out the box the 950 has
more video capability for the same size monitors. The 900 can
do 24 bit with both 13" and 16", doesn't support 19", and
does 8 bit on 21" monitors.

I wonder if anyone knows and can recommend me a good NuBus display
card for driving a 14" multisync ?
The NEC 3D can do horizontal refresh from 15.5 kHz to 38 kHz and
vertical from 50 Hz to 90 Hz and can do max 1024x768 interlaced,
though I am looking for something more like 800x600 or 832x624
noninterlaced.
It would be very nice to find a card which can be programmed quite
freely within these limits and is capable to display at least
8bits/pixel, preferably more.
Is there anything on the market that comes even close?

Can I remove the 68000 under my daughterboard upgrade?
Organization: Occidental College, Los Angeles, CA 90041 USA.
Lines: 26
The subject says what I would like to do, here are the details:
I have a 512ke with the MacRescue upgrade board that makes it the
equivalent of a Plus .
The MacRescue board clips onto the 68000 on the MB. It also has
a 68000 itself. Periodically I have to remove the clip and clean the "legs" of the 68000.
Larry Pina's book asserts that this is occasionally a problem with
snap on upgrades: the 68000's "legs" will oxidize, causing
unusual system errors.
Well, that's me.
So, I would like to do something permanent, and I think it would be
fairly easy to put a socket in where the 68000 currently is, and
modify the MacRescue board to plug in. What I'm not 100% sure of
is whether it will work. It seems to me that the two 68000s aren't
acting independently; so removing one shouldn't have any effect on
the performance of my Mac. I'm about 97% sure.
Will someone provide the extra 3%?

Re: Adding int. hard disk drive to IIcx

NNTP-Posting-Host: carson.u.washington.edu
Keywords: Mac IIcx, internal, hard disk drive, SCSI
Yes, it is possible to add a second hard drive to a mac IIcx internally. This
is definitely not a recommended procedure by Apple but I have done the equivalent to my CX after upgrading it to a Quadra 700. The power supply is still the
stock CX's and it was able to power two Quantum LPS drives, a PLI SCSI
accelerator, a Micron technologies 24 bit video board, Daystar QuickCache,
New Technologies Overdrive and 20 meg of RAM simultaneously.
I added a new mount for the drive by attaching angle brackets to the drive
tower. The internal SCSI cable was changed to a longer flat ribbon cable onto
which I added an extra connector about midway. The final HD was internally
terminated and the drive between the motherboard and final HD had its terminator resistor packs removed. Cooling has not been a problem and no SCSI problems
occur with either the PLI SCSI chain or motherboard SCSI hooked into the two
internal hard drives.
It works very well for me, but proceed cautiously if you wish to do the same.

Quadra Clock Chipping Works
Organization: University of Washington

Summary: Quadra Clock Chip Swap Success
Keywords: Quadra,clock,accelerate
After reading reports from Germany of success in accelerating a Quadra
or Centris simply by changing the clock oscillator, I decided to test the
claim. I pulled out my Variable Speed Overdrive and the motherboard's
50 mhz clock chip. I put a socket in the clock's place and inserted a
64 mhz TTL clock oscillator I had left over from working on some SI's.
I can't believe it. It actually works. I'm not getting SCSI timing errors
either. This is only after a short run time but I'll keep posting results.
Did I spend all that money on the VSO for nothing? If this keeps working,
the lack of a double boot in itself will be worth the effort.

Not in a clock-doubled system. There isn't a doubling in performance, but
it _is_ quite significant. Maybe about a 70% increase in performance.
Besides, for 0 wait state performance, you'd need a cache anyway. I mean,
who uses a processor that runs at the speed of 80ns SIMMs? Note that this
memory speed corresponds to a clock speed of 12.5 MHz.

Content-Length: 1161
Lines: 33
I have an SE/30 with a 80 meg HD which dates back to April 1989. When I
originally purchased it, I experienced the failure to boot problem. This
was fixed soon after by a ROM upgrade on the hard drive.
Lately a similar problem has been occuring. When the computer is
powered on the HD light flashes a few times and then I am given
the "no disk to boot from" icon. However, upon turing the
computer off and on again the drive ALWAYS boots up just fine.
Furthermore, if instead of turning the power on and off I press the reboot
button the same problem occurs. But, as I said, turning the power
off and on always works.
This problem is different from the 1989 boot problem in that before
it often required several power off and ons to get it to boot.
Does anybody have any suggestions as to what the problem is or how
it can be fixed?
I'm wondering if it's getting old and requires more time to
"come up to speed" now. Is there a PRAM or SCSI setting that
allows me to tell the computer to wait a little longer before
trying to access the HD?
Thanks!

I'm having exactly the same problem. Again, it's fine when I switch to 16
colors or a smaller monitor. My configuration is:
Model: Centris 610 with 4 MB/80 HD, 512 VRAM, no cards
Monitor: MAG MX15F with 16" monitor adaptor
I just discovered the problem a little while ago after plugging in my
new MAG monitor. It seems to appear either when scrolling through a
window or when using Alpha or Word and I enter <return>.
My guess is bad VRAMs as well. I really hope it isn't a design flaw. Is
anyone at Apple listening?

Well, I just got my Centris 610 yesterday. It took just over two
weeks from placing the order. The dealer
appologized because Apple made a substitution on my order. I ordered
the one without ethernet, but they substituted one _with_ ethernet.
He wanted to know if that would be "alright with me"!!! They must
be backlogged on Centri w/out ethernet so they're just shipping them
with!
Anyway, I'm very happy with the 610 with a few exceptions.
Being nosy, I decided to open it up _before_ powering it on for the first
time. The SCSI cable to the hard drive was only partially connected
. No big deal, but I would have been
pissed if I tried to boot it and it wouldn't come up!
The hard drive also has an annoying high pitched whine. I've
heard apple will exchange it if you complain, so I might try to get
it swapped.
I am also dissappionted by the lack of soft power-on/off. This
wasn't mentioned in any of the literature I saw. Also, the location
of the reset/interupt buttons is awful. Having keyboard control for
these functions was much more convenient.
Oh, and the screen seems tojump in a wierd way on power-up.
I've seen this mentioned by others, so it must be a...feature...
Anyway, above all, it's fast. A great machine at a great price!

This doesn't sound right to me. Don't Quadras use the 53C96? If so, the
Mac has nothing to do with the SCSI timing. That's all handled by the
chip. About the only the timing could be wrong is if Apple programs the
clock registers wrong on the 96. That, however, should only really hurt
synchronous transfer, which is not used by the Mac SCSI Manager.
Furthermore, disabling blind writes should be meaningless on a Quadra.
On Macs that used the 5380, which is a much lower level SCSI chip, the
Mac was responsible for the handshake of each byte transferred. Blind
mode affected how the Mac handled that handshake. On the 5396, the
handshake is entirely handled by the chip.

I have a Radius Precision Color 24x video card for the Mac that fits in a
NuBus slot. The card has 3 Mb of VRAM on it, which means that 24-bit color
is possible on the card! The card supports just about any monitor scan
rate you can think of . You can switch resolutions and depth on the fly with a
software control panel.
This is the ACCELERATED version of the card, which means all QuickDraw
calls are not executed by the CPU but taken over by the video card, freeing
up the mac processor for other tasks.
The cheapest I could find this card for when I called around last night
was $1738 at Mac's Place. I will sell it for $1250 + shipping. It is just
over a year old and never been any problem. It comes with software and the

The Partition button in Apple's HD Setup lets you set up A/UX and other
types of partitions. It WON'T let you create more than one normal mac
volume. You need SilverLining or something similar to do that. It WILL,
however, allow you to take advantage of some possible unused space on your

No the continued develeopment is because there is becomming less and less

to make the money in software , after all you can sell multiple pieces of software to ONE

As you also said Windows is a nightmare for programmers, so will the

The original Mac II had an Apple MMU chip installed which performs a subset

The problem is that the pins in the ADB connector

port. If you take it to an Apple Repair Centre, that

It means that either my display memory goes wrong or monitor is bad
or video card is bad.
I checked my monitor, it works fine with other Mac.
I checked my video card, it's also fine.
I replaced all the RAMs, it still didn't give me right answer.
Hence I assume something wrong with some part of my motherboard.
I don't know hardware architecture of the Macintosh.
Can anyone tell me what's the problem ????
It's a Mac IIcx.
MANY THANKS IN ADVANCE.

It is very possible to connect another internal hard disk in any
macintosh if you can find the space to put it. I have a IIsi that came
with a Quantum 80 meg drive. When I ran into space problems, I slapped in
another 40 meg quantum that I had sitting on a shelf. Here is what I did.
First off, I was concerned about space. Since both drives are Quantum
quarter height drives, I finally decided that the logical place for them
was stacked one upon the other. Fine, they fit snugly. (I have not had a
problem with heat yet, and these drives have been running together for
over two months.
The next problem was connecting the drive. If you have a spare internal
hard disk power cable as I did, then half of your troubles are over. just
splice in the extra cable so that you get one square motherboard
connector and two hard disk power connectors. If you don't have a spare
cable, you will have to buy the wires and connectors which can be found
in any good electronics store for about $10. I would suggest properly
soldering/heatshrinking the connections to reduce the possibility of
shorts or bad connections.
Next, you need a ribbon cable connection. Again, I had a spare hard disk
ribbon cable, and I wanted to be careful in case this didn't word so what
I did was purchase a crimp on 50 pin cable connector that gave me another
male connector in the middle of my spare cable. The part cost $10 again,
and is easily attached with any good wood vice. The theory behind using a
crimp on connector is that if this doesn't work, my original cable is not
damaged, and I can go back to the original setup.
Having done all that, I couldn't be bothered to check the dev notes for
power consumption so I plugged it in and it works like a charm to this
day.
In a mac II, everything should work the same. Be careful with the ID's of
the drive, and ensure that the terminating resistors on both drives are
intact. I did not try this without the terminating resistors but it
seemed logical that if I am splitting the SCSI chain, that the signal
should be terminated at all the ends.
Let me know if you have any more questions.

TCP/IP routing LocalTalk-Ethernet.
Organization: University of Michigan ITD Consulting and Support Services

Here is the story:
I have a network with 4 Macs on Localtalk. One of them has an
Ethernet Card, and is currently connected to a NeXT . The NeXT is connected
to the internet over SLIP running on a 9600 baud modem.
Currently, we can telnet from the Mac w/ Ethernet to the NeXT,
and then telnet out again to the rest of the world.
What we want to know is if there is some sort of hardware that
will route telnet sessions from the Localtalk Macs to the NeXT
via the Ethernet Mac. From what we have heard, AIR doesn't do
the trick.
Software solutions would be good too, but my impression is that
there aren't going to be any.
Our immediate interest is to be able to get to the NeXT and telnet
out again. The SLIP connection doesn't allow us to assign IP numbers
to machines, so everyone shares that 1 number...oh well...
thanks in advance.

Well Bill, There are 2MB soldered on the logic board and 2MB in the RAM
expansion slot giving you 4MB. The only thing you can do to upgrade to
the maximum Ram is to remove the 2MB expansion and install a 6MB expansion,
giving you a total of 8MB which is the max on a 170....You can try calling
TechWorks, or any other memory vendors out of MacWeek, MacWorld...etc....

The point being the processor speed is only one of many aspects of a
computers performance. Clock speed, processor, memory speed, CPU
architecture, I/O systems, even the application program all contribute
to the overall system performance.

Sorry about the misinformation. I made a bad assumption about
the new machines behaving like a Quadra 900, see previous
post. About sampling the CD audio though, have you tried it? I
found the aliasing to be really bad. Like it needed a filter or something.
Much worse than I expected. I installed the CD-300 in the

Replacing internal FDHD w/ floptical?

Re: IIsi clock upgrade
Organization: Idaho State University, Pocatello
Lines: 47
Hi, I have been getting a lot of requests for this information so I thought
I would post it for those interested parties. .
To increase the MacIISi speed to 25MHz or 33MHz the clock must be changed
from 40MHz to 50MHz or 64MHz respectively.
This is done by going to a static-free work station or putting some
aluminum foil down to work on.
1. Open up the Si by lifting the tabs at the back of the case.
2. Remove the Hard Disk by disconnecting the power and SCSI cables,
spreading the tabs, and lifting the drive out.
3. Remove the flopy drive.
4. Remove the power supply by spreading the tab in front and lifting
the supply straight up and out.
5. Remove the fan by pressing the ears together at the back, bottom
side of the fan and lifting straight up and out.
6. Remove the Mother Board by spreading the tabs on the left and
right side of the board and sliding the board forward then
lifting the board out.
7. Desolder the 40MHz clock .
This is not easy even for a skilled solderer.
8. Get an IC socket with the round pins and remove four of the pins
by pushing them up from the bottom with long nose pliers.
9. Put the four pins in the holes vacated by the clock and solder
them in.
10.Insert a 50MHz or 64MHz clock.
11.Put large power transistor heat sink's on the processor chip and
the other large chip just to the right of the processor and
figure some way to hold the heat sync's in place. I made a
simple clamp by putting a four inch screw up through the hole
in the board between the two chips. Mount the screw using
insulated washers. Screw a cross member down over the heat
sync's to hold them in place. Don't use too much pressure.
12. Put it all back together and go-for-it.
Disclaimer: this is only the procedure I used and is not authorized by anyone.
You are on your own for this procedure. I'm quite sure it will
void your warentee.

Re: Quadra 700 Sound
Organization: University of Tasmania, Australia.
Lines: 23
The Quadra 700 goes thru extensive initalize routines of its hardware,
read's PRAM, obtains all info from last session including the volume
setting, and then executes the sound procedure for the startup sound, and
wait's on the SCSI controller to respond to the boot up code.
If the DRAM produces an error, or a registers cannot be read from a device,
or the device corrupts that address/data or control paths, then if it is
possible, the firmware branchs to another sound routine that produces the
'sad mac' sound.
This is a general breifing of the start up procedure of a typical mac.
If you cannot control the volume of the quadra, even at boot up, then i feel
there is something incorrect with the logic board.
My Quadra 700 does not show the problems you are having.

The original poster posted an item saying that he had bought a new
wizz-bang Laser Printer from Apple which can print
GrayScale. He then said that he CANNOT PRINT GRAYSCALE from his SE computer
.
This is the one major bugbear about doing a 3rd party SE upgrade : you will never be able to run Color Quickdraw. It
is Color Quickdraw that controls Color AND Grayscale.
SEs CAN print some COLOUR: this is because Quickdraw - the original, non-colour
version, has the right hooks for eight colours. Some of you will remember the
'SCSIgraph' solution to getting a colour screen for your SE .
There is no reason that Apple couldn't release software patches for older
computers - but they wont, and 3rd parties are having a difficult
time in duplicating the Mac's ROMs .
Just one Caveat: I would have thought that if you were printing a POSTSCRIPT
Grayscale image onto a POSTSCRIPT Grayscale printer, that you would be able to
do so, whatever Mac you were using. .

Try Goldstar. They make them, and they are available immediately in Mac

Trade Mac SE system for Color Mac???
Article-I.D.: wixer.1993Apr16.181557.11264
Organization: Real/Time Communications
Lines: 31
Ok I want to get a color Mac I don't care if it is an LC or a Mac II or
what but I want to go to a color machine. I'd prefer to trade my
present Mac SE system plus some cash or other equipment for the color
system as right now I'm not full of the $$$ to buy a color system
outright.
Here's what my Mac SE system has...
Mac SE 4/20 with internal 800K drive
20 Meg external
External 800K drive
ImageWriter II with 4 color ribbon
Stuff that can go with it......
I've got 3 modems and I'd be willing to give 1 of the 9600's and the
2400 with the system
MultiTech Multimodem II
U.S. Robotics Sportster
Microcom QX/12K
The USR and the MultiTech are both brand-new

Ethernet to LocalTalk On a Quadra?

I have used both my serial ports with a modem and a serial printer,
so I cannot use Appletalk. Is there a Ethernet to Localtalk hardware
that will let me use the Ethernet port on my Q700 as a Localtalk
port. Until they come out with
satellite dishes that sit on your window & give you internet access
from your home, I won't at all be using that port.

the Q700 will only do 8bit or 24bit color. if you want the higher
color depth, it's 2MB's of VRAM altogether for a monitor up to 16".
for a 21" monitor, you can get 8bit max.
hope this answers your questions.

What you need is a hardware router such as EtherRoute/TCP made by
Compatable Systems . This will allow you to connect your Localtalk
network to your Ethernet network . It will
route TCP/IP protocol between the two networks. Software routers are also
available for less money, but I'm not sure if they work with TCP/IP.

* the Sony CPD-1304 has better video circuitry than either of the

small anyway so it might not be that useful.
Note that with either Sony monitor, you will need the proper adapter,
which both connects the video signals properly, but also informs the
Macintosh video hardware of which display mode to use.

I'm assuming that the cabling tells the Mac, at startup, what kind of
monitor is connected. Now I think I've seen ads in popular Mac
magazines for products that allow you to change resolutions
on the fly .
If you were to buy a 1304, would it be possible to switch back and
forth between Apple 640x480 and Apple 832x624 without restarting the
Mac? Is this strictly a hardware startup function, or can software
intervene, or does the Mac hardware occasionally probe the cable
setting and switch automatically?
Thanks,

My Datadesk Mac 101E keyboard has similar problems. I have found that

Similarly, I have trained myself to hold down the RIGHT-HAND pair of
