I have had *exactly* the same symptoms with a Rodime disk with Rodime's
own Cobra driver. Run DFA on it and it would give an error, and even
without quitting DFA, run it again on the same disk and it would say it
was OK. Norton finds nothing wrong. This has been going on for me since
System 7.0 (perhaps even longer), and its not new to 7.1. In the end I
have just learnt to ignore it. The disk itself seems OK.

Subject: Problem with Quantum drive and Quadra950
Date: 22 Jan 93 20:16:28 GMT
Organization: Universite de Montreal

Sorry if this is something asked before but I could not find
any references to it in the last 1000 messages...

I'm trying to install a Quantum prodrive 210(S) as an internal
second disk in a Quadra 950. I removed the terminators located on
the disk (controller) and connected it to the SCSI cable coming
from the first disk (this cable seems to be terminated, correct?)
, and plugged in the power-cable from the B-outlet on the power-supply 
to the disk. I set the jumpers on the disk to have ID 3 (I think, I tried 
different settings anyway). 
When the computer starts up the disk spins up, it makes some noises
and the little green lamps blinks once and then it becomes quit. 
The Mac boots up on the first disk but my Quantum wont show up.
SCSI tools can't find the disk (when they scan the bus for
SCSI-devices the lamp on the disk blink again).

So my questions are;
-Is the Quadra internal SCSI special in some way?
-There are 3 jumpers marked SS,EP,WS next to the SCSI-ID pins.
 EP is connected, leaving SS and WS open. Is that correct?
-Should I give up and buy a external case for my drive,
 and will it work then?

Thanks for any kind of advice.

Yes... but... There are a couple of factors to check first. Do you have enough
power available in the stock IIsi power supply. Do you have the space
available. If the answer to these questions are yes then... Yes you can!

You will need to either purchase, contruct or have constructed a replacement
cable for the 50 conductor ribbon cable currently connected to your internal
drive. This cable will need a third DIP connector attached in-line for the new
drive. If a second Power supply connector isn't included within the case (It
is in my IIci!), you will need to get one of these also. I say to get a
replacement because if you ever need your IIsi serviced, you will need to
convert it back to the original condition, or you Apple Dealer my refuse to
work on it!

To install the drive, you should figure a way to mount it so it will not move
internally when the computer is moved. Place jumpers on the address lines of
the new drive to set it to something other than zero (first drives address) or
seven (the Macs address). Remove any "Terimnation" resistor packs from the new
drive. Now install the new drive to the inside connector of the new cable
(Make sure the cable is alligned (pin 1 to pin 1), and the power connector.

Your new drive should now be ready for formating. Remember, if after doing this, your Power Supply burns out, Apples NOT gonna fix it!

Good Luck

Hello

	When is the Apple CD300 EXTERNAL cdrom drive going to be available?
The dealers I've talked to have no info on it (not even price).  Anyone know
the following details:

	1. Price without Educational discount?
	2. Price with educational discount?
	3. Availability (ship?) date?
	4. Disks included?
	5. Cables included?
	6. Driver software included?
	7. Multisession Photo CD compatable?
	8. Do I need system 7 to run it?

	Would I be better off with the Toshiba 3401 for $679 or the NEC CDR74
for $659?  Are these better drives?  Does their performance outweigh the
benefits of having an Apple Drive (ie long term support of the product)?

Any and all input appreciated.

That's certainly the case with the NeXT, there are a lot of new apps in
development, etc. The thing that bothers me here is that they are typically
non-standard applications by newborn companies. PasteUp is supposed to be
a great DTP program, I hear - but personally, I would have rather seen
Quark or PageMaker ported over to the machine first. There are some major

and Frame are the biggies, but IMHO, the lack of these drives away those

 We have the Apps out on the net, but they do boot locally. All of our
 machines have 16 megabytes, but I have used those with 32 before. A lot
 of the more processor intensive things [like intense math] still run the
 NeXTs into the ground. I feel they often don't do things as fast as the
 Quadras can -- simply because Apple and the other companies have to
 streamline to get their programs to work on lower end machines like the
 Mac Classic.

I guess I didn't make myself plain enough with what I've noticed. Many people
took the time to explain what random numbers are and how they work. Thanks.
But what I'm seeing is a little beyond that. For example, playing Tetris,
I'll get 10 of the same piece in a row, the a little while later 12 of
another piece in a row, and a little while later a lot of another piece.
Tetris keeps statistics of pieces used and it doesn't look too random to
me - 50 of one piece, 40 of another and 1 of everything else.

Another example - Spaceward H0! - when I have it create a scenario with
computer players, 8 times out of ten the enemies will be on planets right
next to me no matter how big the galaxy is. If I make a humongous galaxy
and one computer player, I would think that it would not consistently be at
one of the eight planets surrounding me.
 
I could give other examples (like everyone getting a large number of yahtzees
in a single game, usually with the same number). If they had happened once
or twice, I could understand, but it's pretty consistant.These things did
not occur on my Plus.
 
But then again, maybe this is how it is supposed to work.

If its a standard 8-pin serial cable on both ends (like the imagewriter cable),
then it should work just fine.  In fact, at my school in the computer lab, I've
disconnected the Laser writer's appletalk connector and used it to gain access

NeXT's could use some more power, that's for sure. The 586 and HP (maybe)
ports should help that.

Also, one has to consider the overhead of the object-oriented software. Almost
no NeXT software is optimized with assembly (I may be wrong, but it kind of
breaks the whole OOPS thing, not to mention portability).

And there is a lot more going on on a NeXT than a Mac. 

Overall, I'd agree that NeXT's aren't as fast as they should be. They aren't 
dogs, but I don't think they've found the best platform for the OS.
Hopefully, that will be solved this year.

Hi there.  I just bought a Macintosh the other day, and I was wondering
if there was a way that I could use my HP DeskJet Plus with it to print
out Mac douments.  The DeskJet has a serial port on the rear, so I
could hook it up through the printer or modem port on the back of the
Mac.  The only thing I would need would be a system driver for the
chooser.  Is there one around?  Maybe in the Public Domain area?  Is
this possible to do with my equipment?

MIP = Meaningless Indicator of Performance.  Suffice it to say that
both can be roughly 4 times as fast as the current Quadras.  More
acurate number are, by the way, irrelevent.  CPU MIP ratings are also
irrelevent (as an example compare the IIvx and the IIci).

Probably 32.

No.  Parallelization (I went to Stanford to learn that word.  It doesn't
turn out to be anywhere near as useful as you might expect.) is much
more a software issue than it is a hardware issue.  The 68020 had
support for parallel processing.  See many multi-CPU Macs around?

Superscalar mean that the CPU is smart enough to execute two instructions 
at the same time when they don't conflict with each other.  That means 
two instruction pipelines.

Parallelizing CPUs can potentially lead to 1000 fold speed increases.
As yet, success towards that goal had been somewhat limited.  Also note
that having two CPUs is a lot more expensive.  If you really need the
performance, you should be looking at a workstation.

Besides keeping the paper in a moisture free environment (i.e. open

flipping it over on the second pass. You don't have to print anything
on the second pass, as long as it goes over the fuser.

On the other hand, you can buy a NeXT today and have what Cairo and

Or, you can wait until June and buy NeXTSTEP '486. And maybe, by the

Or NeXT's Risc workstation which will hopefully be out this year. 
(And which may be based on the Power PC)

Somebody'll probably mention that NeXTSTEP isn't "totally" object-oriented.
