Argh! I looked at the package for like 12 msec, hefted it for 29 msec to see
what kind of noise it made / how the internal mass felt, and _guessed_, based
on 17 nsec of thinking about it, that 'I suspect ... 8" floppies'.
Had I stopped to think, I probably would have come to the same conclusion:
for original PC; original PC only had 5.25 inch floppies (which I had to look
up, I couldn't remember off the top of my head - my first was a KayPro AT)
--> probably 5.25" media inside - but I didn't, I wasn't that interested, I
just wanted to find a good home for it!
(And no doubt the seller made the same mistake, which was why it was in with
a bunch of 8" floppies...)

Chris Elmquist has kindly put my hand-drawn reverse-engineered schemtatics for the DEC Rainbow on his
'google drive'. You should be able to download them from the link below (I have checked, I can access them)
This covers all the parts of my (rather complete) 'bow, including PSU, drives, expansion boards and monitors.
Please let me know if there are any problems.

In case anyone is interested, I whipped up a little CARDIAC
simulator as a JavaScript exercise last night. You can find
it at:
http://cs.drexel.edu/~bls96/museum/cardsim.html
If you were at VCFSE this past May, you may have seen a
short presentation I gave on the CARDIAC. If you're not
familiar with it, it was an educational tool developed at
Bell Labs back in the '60s to teach how a computer operated.
CARDIAC stands for CARDboard Illustrative Aid to Computation.
Enjoy,

Hi, all, along with some 8" floppies I just bought, I got a copy of "Hayes
Smartcom II" which I have no use for, so it's free to a good home (but the
receiver has to pay for shipping). FCFS.
It's NOS, in original plastic wrap (which I don't want to open, so I can't
tell you what's in it, but I suspect manuals and 8" floppies): the label
says "For the IBM PC .. and compatibles: Version 2.2: DOS 1.1, 2.0, 2.1,
3.0 or 3.1". It has a 1985 copyright date on it.

Hi,
I'm looking for copies of DECnet-11M 2.0 or 3.0, which would be paired with
RSX-11M 3.2 or 4.0. If anyone has a copy that isn't already out there on
the web, it would be much appreciated. I may actually have a copy, but we
haven't yet recovered the tapes that came with this machine.
Thanks!

Trying to help out a friend, he's unable to get the mouse working on his
Amiga 2000. We've determined that the +5V line(s) on the DB-9 controller
ports are dead, which would tend to account for the non-working mouse. That
is, I assume the mouse electronics draw their power from the +5V pin.
So the +5 pin on each of the two ports lead back to a common point, which
is a fuse.. thing is, it's a surface-mount fuse, and it's marked 4A.. as in
FOUR AMPS.
Now the schematics we have do show the fuse, I believe it's indicated as
F1. But there's no rating on the diagram. Can anyone confirm that this is
actually a 4A fuse? Why on earth would they have such a high-rated fuse
protecting those lines?
What sort of controller-port peripheral device could ever need that much
current - and is a common DB-9 connector (or for that matter, the PC board
traces) even capable of that kind of current?
400mA maybe?

Someone pointed out to me that it's probably actually 5.25" floppies; the
original PC did come with 5.25's. The box size just looked the same as the 8"
floppy box, is why I assumed 8".
Like I said, I'm reluctant to unseal the box to confirm it's definitely
5.25", though.
