I have an IBM AT Multiprotocol Communications Adapter, new, in the
original carton, with the original vinyl booklet and 5.25" disk for
sale. It's only missing the cable which can easily be made from two 25
pin d-sub connectors (1M, 1F) and a piece of cable.
Anyone in the US want or need this? $10 which includes the postage. It
goes to the big dumpster in the sky if no one lays claim to it by Friday
the 10th.

Does anyone have an ESDI hard drive for a PS/2 Model 70? I have a
60, but want to replace it with a 120 (the other size the PS/2 came
with; I don't want to risk having an incompatible hard drive). I
don't know if others are compatible. However, this is a wide single
ribbon connector.

Serious answer... pulling is more reliable then pushing.
Also if that thins is like my LQ5000 and the LQ570 it can be set up in
push mode.

Actually, my favorites are the ones where the tractors are right
on the platen. No jams and no wasted paper. I once had an Epson
MX-150 that jammed something awful. I got rid of that. An example
of the former is the Okidata 120, which I used with my C-64. But
to tell you the truth, I can't stand wasted paper almost as much
as wasted hardware ;)

Thanks, Tim, that's what I was thinking of. And thanks to whoever dug out the
posting (sorry no attribution, I hit "delete" a bit too quick). Seems my
memory was close but not wholly accurate. How unusual :-)

We had several, but they all got cannibalised. They were indeed Z80-based, and
had lots of SIOs, DARTs, and a few PIOs in them too. Neat cases as well.

I've no idea. I imagined that Camtech made other ethernet stuff, and if they
could make such a good-looking QBus ethernet i/f I thought there must be more
around. I've never found any, though, nor have I ever found anyone who could
tell me much about long-gone Camtech (apart from JNT PADs).

I looked at the pictures, and double checked my Olivetti M24, recently
obtained from Andrew Davie. They are the same machine.
This one also has a dead power suppy but none of the corrosion. The fan
works because it is mains powered, 240v in this case.

Subject: AT&T 6300 PSU Question
I went to power up my AT&T 6300, which hasn't been up for about 4
years, and noticed that the PSU fan was coming on but the drives and
motherboard didn't seem to be getting power. I opened up the system
and was surprised to find the power supply was corroding. Now I'm
not a PSU expert by any means so this was unexpected. The upper
motherboard appears to be ok but I haven't checked the lower
motherboard yet. It appears I can pull the PSU out and replace it
but I'm curious as to why it began corroding in the first place. You
can see pictures of it on my web site on the AT&T 6300 page or at:

Speaking of shortwave, imagine if the FCC authorize commerce on
ham radio! Ugh...
I am completely unfamiliar with S-100 systems, so could you please
explain... were S-100 technologically superior to PCs (i.e. IBM
PC 5150), or just aesthetically? As far as I know, they used an
older processor...
Was it just an issue of being used to them?
As for laissez-faire, I never have believed in it. It makes society
too concerned about money. This is proven when complete crap hardware
is released now, and people don't care because it's good _financially_
