Yes, it's a 10baseT transceiver. Lots of companies made transceivers to
fit Macs, because the Apple ones were expensive. I've got ones made by
Asante and Farallon. Allied Telesyn made the best (IMHO) ones, and had a
whole range including fibre transceivers. There are some made by Sun that
look the same -- but they only work on Sun workstations (different pinout).

If anyone here has a PDP 11 (such as a 44/84/34) or Vax 11/750 or 11/780
for sale, or know someone who does, could you let me know?
I checked on a Vax 11/780 for disposal in Ohio but it went to the landfill
already. * Sigh *
I really appreciate it. Thanks!

I just got back from a trip and found a box of DEC FlipChips in my front
hall! There's a fair number of them that appear to be new -- they're in
little plastic bags, still stapled shut. Here's what I've counted so far:
1 A704 -10V power supply (double size)
3 B113 unused
3 B200 unused, 1 used
1 B401
1 B405 unused
4 A601 unused
1 A604 unused
1 R002
1 R107 unused, 1 used
4 R111
3 R113
2 R123 unused, 2 used
9 R141
5 R202
5 R203
6 R204 unused, 1 used
1 R302
1 R401
1 R405
1 R601
2 R603 unused
3 R650
1 S111
1 W650
There are also a bunch of "Flip Chip Modules Test Specs" data sheets with
specs and schematics on them. I'll scan them and post a URL to the list.

A local electronics surplus store that I have frequented for years is
going out of business next week (sigh). During this week's visit, the
proprietor offered me a pallet of 10 'complete, working and loaded' PDP
8e's. When I asked what he wanted for them, his response was the
typical 'make me an offer'. I got the feeling that if I passed, they'd
end up on ePay.
My collection is mostly 80s-era 8-bit micros (Apple, Commodore, etc),
and Heathkit test kits; the only piece of DEC-ware I currently have is
VAXstation 3100, so I have no idea what the PDPs are worth. If I take
these things off his hands, what would be a fair offer?
Cosmetically, they seem to be in great shape, and he powered a couple of
them up for me (blinkenlights and such). I opened several of them up,
and they were all filled with various cards. Space considerations
probably will only allow me to keep two or three; I'll offer the rest
here - whatever doesn't get claimed will be put on ePay.

Actually the human visual response in variable depending on what part of the
field of vision is used. I can and many people can see flicker using your
peripheral vision. Pointing your head away from the screen about 60 degrees
and looking at the screen from the corner of you eye you can commonly see
flicker. Rods and cones in you eye respond differently to color, flicker,
and light levels.
There are whole books on human visual response and lots of study of the
field when looking at Radiological images. The new "hot topic" is Radiology
is "soft-copy" reading of medical images, skip the film use a computer
monitor. The problem is that clinical quality monitors cost
$10,000-$20,000. Everybody want consumer grade monitors with the associated
low cost. Brightness variability across the screen is routinely 25%.
Examining images for lung cancer nodules or mammography lesions are
examples. There is a huge equation that lists visual response which is tied
to brightness, apparent contrast, wavelength, and size. Lots of human
response is below the "threshold of awareness". If you can obviously see
the lung nodule then your chances of treatment and 5 year longevity are
reduced.

It may be too late for me to get more, but I found a case of Micro
Integration 5250 Gateway products, looks like an ISA card and software
for a PC to talk to a twinax AS400 system. I have a couple, may be able to
dig out more, any interest?
************ Note the correction the company is Micro Integration, and I
will dig and see if I can get a few more since there seems to be some
interest. The boxes contain an ISA card, software, and a short adapter to
TwinAx from something like a RJ45 I think. Some mental blur exists.
John,
This is actually where I started my search. This has now become a quest for me. I did get a response from someone on the list who said they had the whole series on one tape but I haven't heard back from him. A friend of mine who besides being a VMS guru does audio/video editing, said his father had connections at a local PBS station and he would see what he could find for me. If I do find it, I will definitely make it available to the list.

What sort of digital interface would such devices use? They'd have
to have lots
of wires, e.g. 26 or so pairs, if the thing is using 24-bit color.
Perish the
thought someone would use more color depth than that! It's hard to
imagine
they'd do that. The number of wires that have to transport
high-frequency
signal is the reason the analog is still so difficult to surpass.
Not if a serial video bitstream were used. It's actually easier to use this
than
an analogue feed over any significant distance.
