I asked about the existance of such a product a while ago, seems its extremly
discouraged by the RIAA.

Anyway, working throught the numbers, I found that the serial port would
not cut it. You "almost" have it, but don't forget, music is stereo!

not even with external clocking is the Mac serial port rated for 1.44Mbits

A SCSI device might do the trick though.... 

PS, this is also why all those CD-ROM players that can play music don't
    let you read the digital music, RIAA would smote them with a lawsuit as
    big as Canada if they did.

I'm VERY suprised at your difficulties with the Supra.  I regularly
connect to a v.32bis line in Cambridge, Massachusetts while I'm in
Portland, Oregon without a single problem.  I connect to various
bulletin boards and friends modems anywhere from v.32bis (14,400) down
to 2400...  Perhaps you should talk to Supra about the possibility of
having received a lemon...

Good luck!

 Exactly. The switch takes just a few seconds and HP supplies a nice little
 "house" for the cartridges when they are not in use. The driver will prompt
 you to switch cartridges as needed, or you can just tell it to use whatever
 is installed, regardless. If the black is installed, for example, and you
 print color, you will get grayscale. It's well integrated.

to Apple's 13 inch color hi res monitor but a bit cheaper?

Also, what's the cheapest way to add a math coprocessor to a IIsi.

TW> I have finally received some grant money to up my Mac IIci.
TW> Now I am struggling with the many options available, and I

Here is a summary of the responses that I have received so
far:

(1) The Quadra upgrade is (almost) as fast as any of the
    other alternatives, but is original Apple. Plus one gets
    extra goodies such a a better SCSI, video circuitry, and
    onchip FPU. 
(2) No compatability problems and only happy users with
    Daystar Power Caches. Might be upgradable to coming 040
    versions. 
(3) Fusion Data System Tokamac CI can run A/UX only by
    handing control over to the original 030 processor.
(4) Radius Rocket is also worse than Quadra as far as
    compatability is concerned.
(5) The Quadra overdrive card goes into the Quadra ROM slot,
    and "bumps" its CPU to 33Mhz.

As far as the Quadra upgrade is concerned, this raises a
second question for me. I believe that the Quadra upgrade
will bring a IIci to a Quadra 700. Now I am under the
impression that the Quadra 700 has only 4 SIMM slots. I
currently have 32MB memory in my IIci, which I do need (8 x
4MB). Does this mean if I get the Quadra upgrade I have to
either go back to 16 MB (4 x 4MB) or shell out the extra
money to get 2 additional 16MB SIMMs to bring me to 40MB (2
x 16 + 2 x 4)?

I sure hope not. This sounds way to foolish to be true.

Also, in case of a third party upgrade board, does the
presence of the second board disable the original CPU? Or
could one write programs which actually would use both CPU's
in parallel? I do realize that this would of course not be
available for applications, but could one (in theory) make
use of both CPU's? I have once toyed with the idea of buying
an IVORY board which allowed just that, and I cannot see any
reason why it should not be possible with a "normal"
accellerator board.

When I first got my PB100 and noticed the lack of a Modem Port, I was
wondering the same thing, especially since my modem at home is external
and my PowerPort/Gold isn't here yet... :-)

Anyway, it's called (oddly enough) "Second Serial Port Card".
Here's the description:

The Second Serial Port Card fits into the internal modem slot of the
PowerBook 100 computer and gives the user a second RS-422 serial port for
instrumentation, or an external Modem Channel-A port for connectivity.
When this card is installed in the modem slot, its mini-DIN 8-pin connector
uses the panel space designed for the modem's phone jack.

Hi --

I once spent a week finding out about PSU's on Macintoshes:
which ones had the autoranging power supplies and so on.
I need machines which work in the US, the United Kingdom,
and France.  The first has 110V/60Hz, the latter two 240V/50Hz
or 220V/50Hz.

It turned out that the machine I wanted to choose didn't have the
autoranging PSU, and that Apple makes two versions with different
PSUs, but nothing else different.  (Apple -- if you're listening,
the autoranging PSU is a GREAT feature; a 110/240 switch is
alright, and fixed-voltages PSUs are TERRIBLE.)

So, netters, can you tell me where I can buy either spares or 
third party bits?  Also, I think Apple told me that you can't
buy the 'foreign' PSU in the US?  Anybody know anything about
this?  (Apple?  Still there?  It took four hours of phone calls
to dealers and two hours of phone calls to Apple to find this
out, and then the person was sniffy with me.  Tips: a) get your
800 numbers in directory assistance and b) get your support
act together and treat the customer nicely.)

The Apple part number is 661-0652 "Power Sweep Board (220V) Rev B.",
for the Macintosh Classic II.

Many many thanks for anything people can help me with about
this.  I'm still trying to get into Macland, but have to resolve
this issue first.

Email preferred.

Thanks again,
J.

I'm not sure whether this is blasphemy in a Mac newsgroup, but here goes:  We
have a mixed PC and Mac network, all on Ethernet, with Novell NetWare 3.11 and
NetWare for Macintosh 3.01.

Now the problem is, since Macs can't use more than one AppleTalk protocol
(EtherTalk and LocalTalk) at a time, our Mac people can't connect to the
network without disconnecting from the cheap LocalTalk wiring we have set up
for our 2 LaserWriter IINTs.

We have a couple of choices:
	1.  Hook up the LaserWriter IINTs to PC serial ports.  (It's weird, but
it's *supposed* to work.)  I have an HP LaserJet III with a Postscript
cartridge hooked up to a parallel port on a PC, and it WORKS!  I can print to
that printer from the Macs.  But I've followed Apple's instructions for hooking
up the LW IINT to a serial port (null modem; 9600,n,7,1,p; X-ON/X-OFF; etc.)
and the green light on the printer blinks, but it quits without anything
happening.  I'm almost sure it's a serial port settings problem, but I don't
know what else to set!
	2.  Buy 2 Dayna Etherprints.  Each costs about $399, and I'd rather not
have to do this unless it's necessary, and *absolutely* foolproof.
	3.  Buy Apple's Internet Routing software.  I have no idea how this
works or how much it costs, but I understand it can let Macs route between
LocalTalk and EtherTalk???

If you have *any* suggestions on these options, especially #1, please e-mail me
at gerstel@a1.quaker.upenn.edu

P.S.  Has anyone out there heard of a Macintosh driver for an HP LaserJet (+,
II, or III will do)???

Get some utility which can change the SCSI ID in software.  (The Pro
105 supports this, and the LPS 40 probably does).  I use SilverLining,
but there's probably cheaper alternatives.  Disconnect the external,
boot from a floppy with the utility on it, and change the internal
SCSI id to something that won't interfere.  Shut down, reconnect the
external, boot from the floppy again.  Set the external SCSI id to
'jumpers', and then set the internal SCSI id to 'jumpers'.

I just got rid of a Maxtor 213 MB drive due to questionable performance.  I 
have decided that I would like to replace it with two external 105Mb drives.
I have decided on the Quantum LPS105 mechanism.  The reason for choosing
two drives is more of an effort to save data in case one of the drives fail.
I have noticed that Mirror, LaCie, APS, etc. all box this model of drive.
Can anyone reccommend a brand, and include the price, if possible?
I also have a few questions:

1) Are external drives slower than internals?
2) Is the Quantum LPS105 a decent mechanism?
3) Is it quiet? (this is very important)

I need to purchase these drives very soon (less than 36 hours), so any info
would be great.  Mailed replies are much preferred.  Thank you.

right?) sporting an average access time of 25ms and peak times of 9ms (with
cache). I have seen it priced around $329-$335.

Maxtor 120 Meg Low Profile Drive--Offers 15 ms average access time, but only a
one year warranty. I have seen this priced around $339-$349.

Basically I am interested in hearing about the Maxtor (reasons I should buy it
over the Quantum) from those who have dealt with one or both drives. Any info
will be helpful in the buying decision. The big hangup for me is whether or
not the Maxtor is a more superior drive to warrant spending $10-$20 more and
gaining roughly 15 more formatted megs.

Thanks in advance.
