I'm going to have to check mine now, since it was originally a stock Lisa 2
before I upgraded it to a 2/5 - it definitely has the drive access light
window, so maybe they were going to add in a LED on the floppy drive?

The early CDC disk drives (like many others I'm sure) has so
much room between platters you could stick your hand in there,
and enough room between the flying heads and the platter that
neither smoke nor dust was a problem. One CDC engineer remarked
to me about how they usually be smoking a cigarette while they
were *polishing* the platters (yes, I know about the stiction
cure joke, Lemon Pledge and all that). Which reminds me of an
MPEG that Elsa included with the Winner3000 drivers... you
watch this video, you'll think it's cigarettes that they're
selling...

I have a similar machine which I would call identical except for the
green-screen. All the "prototype" markings that the auction makes
mention of I have seen seen on my Lisa, as well as the only other one
I've seen. I believe these markings to be common, and that the screen
was a replacement job by a 3rd party. Is this guy misinformed or am I?

Hi everybody,
I remember somebody mentioning the CPT 9000 on this list recently.
Since I just happen to be working on one, I thought I'd post this question
here.
Does anyone know where I can get some of the original software that might
take advantage of the full screen-height? I have a copy of ventura
publisher that was pre-installed, but I assume that its CPT9000 driver is
corrupt. It works with the Herc ega driver, but with the CPT9000 driver, I
just get some strange text-mode blocks.
I also wonder whether anyone's tried Minix on it, and whether that might
address the whole monitor?

Chris

I don't recall the specifics of Unibus...but its bandwidth is commonly
stated as being about 7MB/sec. If that's the case, then it's unlikely
that it's asynchronous. But perhaps it is asynchronous, and 7MB/sec
was just the maximum.

For coax or twisted pair the delay per unit length is given by:-
Delay (Secs/unit length) = Root( (C/unit length)*(L/unit length) )
Example: For RG58-U coax, C=100pF/m and L=250nH/m
Delay = root(250E-9*100E-12) = 5E-9 sec/m or 5ns/m
A pulse will travel 66% slower in RG-58 cable than free space.

I never understand this- why not kick it up to 1027x768 and use the

That way graphics look nice and text is still readable and things

Hi everybody,
For those of you who've read my notes on the MIPS RISComputers I'm trying to
get going, I ask this because I may want to replace the QIC-120 drive that's
missing from one of them with a different model.
I'd like some opinions on tape drives. The drive would need to plug into a
SCSI interface, and I'd like it to fit in a 5.25" half-height bay. That's
pretty much all I'd require from it. It would be nice if the drive held at
least as much as a QIC-120 (about 120MB, it so happens ;), and was
inexpensive and easy to get used.
Any suggestions? What's the going price on DDS-1 these days?

I have a tektronix phaser 340 (which I think is rather less then 10 years
old, but I'm not certain...) that has started saying "Fault 05,000.42:8178".
I was wondering if anyone here is familiar with these printers and/or knows
where I can get a fault code reference for them, because I really don't want
to pay xerox to fix my printer. I have a feeling this is something pretty
simple -- the printer was off for a while (like about 3 months) and then just
started doing this last night. any help would be much appreciated.

Water spray bottle works wonders. 3 spritz later and one of my cats has

Some people say tape works well to keep them off things (sticky side up),
but both my cats seem to rather like it, and I find they stand on it

If the speed of an electron in a wire is equal to the speed of light (IIRC,
it's slower than light), then an electron will travel about 11.80 inches in
one nanosecond, which is the point Hooper was trying to illustrate.

Hi!
Is there any way to connect an apple IIC Plus to a "modern"
monitor?
It has a 15 pin connector that has a strange pin out - and a
composit video out on an RCA plug.
I currently use an apple monochrome (tilt-y tube) monitor
to see 80 col text and a Panasonic monitor to see the color
modes. I have to lug to switch them.
I didn't see the original.
Philip Freidin (www.fliptronics.com) is a friend of mine who is doing a
3.2Ghz FPGA. Yes, it takes a level of skill most of us don't posses but
I've seen it protos running on his work bench. Doing 1Ghz for him would
probably be rather straight forward.

Well, I had some exposure to a Phaser III, but it's been a while, and I
don't think I've ever seen anything like the above message.
I suppose you've gone through the whole "check the cables, make sure
nothing's stuck, check for grilled cheese in the ink-wells" thing? (The one
I used, at least, was a thermal transfer printer. Very nice.)
I might also suggest removing the cables, and if there's a NIC, pulling it
to see if that's the fault location.
Otherwise, it's unfortunate that most people/institutions don't have the
good taste to purchase such printers ;) I'd have liked to have more
exposure to them.

I think if I hadn't gotten to the cat fast enough, she would have...
fortuantly, the cage makes a LOT of noise when the cat would pop it open,
and after the 2nd time, I started using the water bottle.
I can't blame her, I got her as a stray, so rodents were probably her
main source of food (that and it seems Wendy's french fries since she
will claw your eyes out to get to them). I just wish she would start
