I am trying to have a clear-out!
Anyone need some 5.25" full-size full-height SCSI drives?
I have an old 486 Netware server with 3 or 4 in - 1 x 9GB, 2 or 3
~3GB, I think.
There is also a stand-alone JBOD disk cabinet with 7 x ~1.5GB disks +
4 Toshiba caddy-loading CD-ROM drives; all are accessed across 2 x
SCSI2 HD connectors on captive drop cables.
There is also an original IBM PC-AT case, in IBM tower adaptor, with
the original PSU and 3.5" FDD fitted. The motherboard is an MSI thing
with a Pentium 133MHz and 128MB of RAM. It also has an Adaptec SCSI
card with a Panasonic PD optical drive/CD reader.
Finally there is an Elonex WS466 network workstation. This is an
ultra-low-profile 486 network workstation (2"*10"*10", 4cm*27cm*27cm).
I think it's a 486DX2/66. 2xRS232, 1xParallel, 1xSVGA, 1x10base-T. No
internal expansion, no optical drive bay - it's too small.
Happy to ship anywhere if you pay the postage.

If anyone has access to companies that have obsolete electronics and IC parts, I need
some Molex 50-39-5288 28-pin IC Carrier, I'd take a few hundred, up to 1000, price dependant.
Molex stopped making these about 2004, I think the guy said, and no longer makes IC sockets.
I've been going through a few of the online places, but no luck yet.
Hopefully someone has some contacts to ask...
Many thanks!

After a _lot_ of downloading and reading, I've compiled excerpts from the best tube logic theory technical documents I've found on Bitsavers and uploaded it as a merged document here:
http://www.scribd.com/doc/5484436/Basic-Principles-of-Vacuum-Tube-Logic-Cir…
I've included two pages on the IBM 650's capacitor memory just because the concept is so cool to me: a tube written, refreshed and read array of 500pF caps. I wish I could find a more detailed description of it.
If anyone knows of other documents on Bitsavers or elsewhere that contain quality stuff on the tubular logic topic, please let me know and I'll add excerpts from them.
Got this in the mail but the tape systems aren?t of interest to me:

Found your name on a website related to antique computers and
components.??There are some vintage items at our company that we will be
discarding when we move to a new location so I am contacting you to see if
you have any interest.? We have reels of tapes and tape drives that can read
tapes written on VAX and CDC systems.? We also have cabinets for hanging
reels of tapes.? There is other stuff around too like old PC systems and
software that we are just beginning to go through.? So let me know what you
are interested in.? Also if you are not interested in the tapes or tape
drives do you know anyone who is?? I'd rather give them to someone who wants
them then to send them to the recycler.

If you are interested please drop me a line and I?ll forward the contact
info.

You are right on the money. To be done with what I have on hand as much as possible since my success in this effort is far from guaranteed. Right now, we're not talking about anything more ambitious that a demo circuit using five tubes.

I'm just working with what I have on hand. And I plan to use the PC power supply for other purposes, too.
Yesterday I unearthed some unopened Infocom games which will go on Ebay
tomorrow afternoon. What caught my eye was a blurb indicating that games
were available for the DECmate, DEC Rainbow, HP 150 and 110, and TI
Professional. I'm especially interested in the DECmate version. Does
anyone know anything more about these obscure ports of Infocom games?

I don't have experience with paper tape. From the
description it sounds like the oils dissolved the rubber by
acting as a solvent to the natural oils in rubber. If this
is the case, you could try something that can act as a
solvent to the oils, such as acetone.
You'll have to test against a sample tape, and don't assume
that the acetone or other solvent wont remain in the tape
and cause damage in the future. You should try to find a way
to copy new paper tapes or transfer the data to some other
medium.
How much data is in the exposed tape that was damaged? Don't
they have leaders with no data on them? Did the damage
extend into the layers beneath the surface? I'm assuming
that the tapes were rolled up and only the first few inches
were damaged.
I'm in need of a working, complete, Super Serial Card for an Apple IIe
that I recently got. If you've got one that you'd like to part with,
please contact me off list.
I'm also looking for the dip switch settings and 10 pin header pinout for
an Epic Technology "2400 Classic II" modem card. It appears to be an
internal Smartmodem clone glued to a SSC clone, but I need docs on it.:)
Thanks All!
