Subject: 2MB SIMMs for Mac IIci?
Followup-To: comp.sys.mac.hardware

Date: Tue, 10 Nov 1992 16:50:04 GMT

Hi,

I was in Fry's Electronics the other day and found that they claim that the
Mac IIci can accept 2 MB SIMMs.  Apple's Tech Note 176 (Mac Memory
Configurations) doesn't list 2 MB SIMMs as a IIci option.  I'm inclined to
believe Apple, but I wonder if this is one of those things where Apple
didn't explicitly test it, so it doesn't guarantee it, but experience has
shown that the 2 MB SIMMs do work.

If you have experience with a Mac IIci and 2 MB SIMMs, I'd like to hear
about it.

Cheers, Eric

832X624 output as you would get from a Apple 16inch Display. Has anyone had

I have had the EXACT same problem.  I don't know exactly when it
started, but it's been around for at least two years now!  I don't
know what causes it, but I also have an external monitor (Radius Pivot)
attached to my SE/30.

Don't bother getting your drive replaced!!  I had mine replaced for a 
whopping $300+ and the problem eventually returned!

I too would greatly appreciate any information about this problem.

    Yeah, it happens to a lot of old hard drives!!!  :-)

    How 'bout s'more information? Is the drive spinning? Do you hear the
familiar sounds when you turn it on? Does the access light ever blink
when you try to mount it? Are you using DriveWare and will DriveWare
recognize the drives existence? Is the termination and the SCSI ID set

Subject: Direct Data Transfers between PB170 and Mac IIci?
Organization: NASA/GSFC
Date: Fri, 13 Nov 1992 19:51:20 GMT

I have just gotten a Powerbook 170 and I want to hook it directly to
my desktop Mac IIci and transfer files back and forth. I know that the
PB 100 can be hooked directly into the SCSI port of the IIci and it will
be seen as an additional hard drive. But the manual says that you cannot
do this for the 140 and the 170. This should be a basic feature of these
computers, but it does not seem to be.

My question is; what is the most efficient way to connect these two
computers, with a minimum of extra hardware and software?

I'm sorry if this has been discussed before, but perhaps some kind soul
can post a synopsis of the methods discussed previously (if this has
indeed come up before).

Thanks in advance.

Would one of you who live near Fry's and did in fact do the upgrade mind 
buying the chip and socket for me and sending it in the mail? I am confused 
about the correct parts and want to be sure I get the right stuff. I would 
just send you the cash before you even went. I do not think that anyone here
would rip me off and take the cash and not send the stuff, after all it is 
only ten bucks or so. If noone is willing to do this, would the be willing to
e-mail me the tel. no. of Fry's and the exact part numbers? I don't want to 
buy the wrong stuff. I am not worried about getting the stuff in TOO much of
a hurry, as I don't have the time to do the upgrade anyways until about 
Thanksgiving or thereabouts. Besides, I got the same (about) performance 
increase you guys are reporting (sometimes more..) from a 64K LogiCache IIsi
pds cache card. I am fairly sure that this cache card would work with the 
25 MHz upgrade, as I think they sell the exact same card to IIci owners. 
Imagine this, I could go from 1.25 times the speed of a normal IIsi (with my
64K cache card in) to 1.56 times as fast. Wow, that's a lot! (that would be
1.25 times 1.25 for the mathematically disinclined). I get a 40% increase in
8-bit graphics performance with my cache card under Speedometer 3.1, and so
that combined with the big increases I have heard of from others going to
25 MHz would probably DOUBLE my 8-bit performance. Hmmm. Well, it is LATE,
so I am going to go to bed and enjoy sweet dreams of my FAST IIsi...

Remember, if someone out there in Cali could help me out with this, I would
be much obliged!

Especially when they're worried people will stop paying many hundreds more
for ci's and just buy si's and add another $10 worth of work and materials
and have a nearly equivalent (but out of warranty) machine.

Well, that's not what I said. Apple's and IBM's share in the PC/workstation
market is already shrinking. This alliance is aimed at countering other
companies' marketing startegies that have been designed to get more share
of that market.

Joe, what color is the sky in your world? Companies don't build products
for their level of technical excellence. Apple and IBM have no desire
to share technology in order to build better products from a technological
standpoint. Customers purchase products because they have certain needs,
and companies build and sell products that fulfill those needs. Beyond that,
corporate alliances are made for strategic marketing reasons. In this case,
more than anything, Apple wants access to IBM's distribution channels,
and IBM wants a software provider to replace Microsoft, who they're pissed
at for dumping the joint OS/2 effort in favor of their own Windows product.

You may make up your own opinions, but have you been following what's
been happening in the industry in the last few years at all?

Bingo! My si turned a year old the end of September (Happy Birthday!) so is
fairly new. I was stunned the first time I looked inside and saw fancy
4MBit SIMMs sitting there, rather than just some plain old 8 chip cards, and
they are 80ns. Not only that, but the RAM soldered on the motherboard also
has an 80ns designation on it. Really amazing, but I think it could be that
by that point, 80ns memory was so cheap it wasn't worth it for Apple to even
bother with 100ns anymore, so they just threw in the 80ns cards. Thanks, Apple!
Unfortunately though, this means you may not be able to get the upgrade to
work, if your si is too old.

Could someone re-post the details on this upgrade? (Or e-mail them to
me?) It seems pretty simple - replace the 40MHz oscillator with a
50MHz oscillator (after saying the magic words "it's out of warranty
anyway") and stick a heat sink to the back of the '030. What is
Apple's comment on this? Do they claim that IIsi's aren't designed for
it and may not be able to take the "pressure", etc?

It your machine DOESN'T work afterwards, can you restore the old
oscillator and expect it to work again? (Assuming that it fails
because of some marginal problem and not because you stuck your
soldering iron through one of the ASICs by accident.)

It's probably the bearings. I wouldn't try to do anything to it at all. The
drive is getting old and will fail eventually. Plan for it. Backup your
data regularly and put aside $25 a month so when it goes you'll be ready.
Think of the good side. A snappy Quantum 42MB drive will double your
capacity, triple your speed, and cost you less than $200.

Just in case I confused anyone here, you have to have bought the
50mhz '030 PowerCache by November 1st.  I didn't mean to imply that    
you have to have _upgraded_ by November 1st (which would be impossible
anyway, since the '040 isn't out yet).  You have all of 1993 to get    
the special upgrade price, as long as you bought the 50mhz '030
between 8/1 and 11/1.  The deal also does not apply to people who
upgraded to the 50mhz '030 -- only to people who bought it at full
price.

Results:
Well, I followed Joe's advice and bought SIMMs with 8 chips on them and
they work perfectly.  The SIMMs I had tried earlier had only 3 chips on
them.  So much for the "RAM chips and SIMMs must be rated at 150ns
RAM access time or faster", which is all the information that the Apple
documentation provided.  The dealer told me the problem was that SIMMs
for the IBM use a 9th parity bit and the MACs do not, but I think Joe's
explanation is more to the point.

By the way, in the mean time I found RAM Check, a program from ProVUE
that tests memory.  It gave the new SIMMs a clean bill of health, which
was confirmed by hours of actual use.

Thanks to Joe and all others who responded.
