I found these. Does anyone want them? The socketed ICs have been pulled
but otherwise they appear to be in good condition. TI 990/203A Memory card.
HAD 16 4164s installed and 16 empty sockets. TM990/101MA CPU card. HAD a
9900 CPU, four 2114s, two 9902s and two 9904s installed.

Yep, the console had languished at salvage for more than a decade, in
a back corner. Much of the electronics has been stripped, but the structure
is pretty complete and the CRTs and much of the HV is still there.
The 205 carcass is still there, being stripped for gold, no cards left,
just backplane blocks and coaxial interconnect.
I don't know what happened to the ETA-10, but I'm guessing it was sold.

I just got in an XGA monitor. Now, I vaguely remember that this was a
precursor to SVGA. Correct?
Is this worth saving from a historical point of view? I'm thinking yes.
Here's some terse information:

I have scanned 11/34 field maintenance print sets.
They are at http://www.mainecoon.com/classiccmp/
And if I am not mistaken the MOS memory is there too.
AFAIK is MS11 correct, just the suffix letter makes
all the difference (core, 11/44 MOS, etc.)

Is it an IBM 9517? XGA was IBM's hires VGA I think after they made the 8514
display and adaptor. Debuted on the PS/2 models.
I have what I believe is a custom CRT. It has a 12" round face, is
approximately 20" long

.. and has a second one mounted next to it, and a keyboard underneath?
There may be schematics for such a device in the Computer History Museum
archives if so.
I haven't even seen a TE16 capstan roller, but since TU58s have
a similar mechanism to the HP-85 cartridge drives, the following
advice may be of use:

I do not recommend heat shrink tubing as it tends to come off. Test the
repair by retentioning a sacrificial tape (use the CTAPE command on the
HP-85) two or three times in a row. If the tubing does not come off, then
it'll probably stay put for a couple of years.
If you are wondering what is the thickness of the rubber on the roller,
the following picture is of an original HP roller with decayed coating
still in place.

I also had a Compaq Portable III - - it had a 5.25" FDD.
It left the plant 17th March 1988 - the date of my birth!
It got stolen from my grandmother's summerhouse in 1999 - and the
insurance company gave me 1500 dollars for it!
(Disclaimer: It was my mother who 'did all the talking' to the company -
I got a lot of money because of the proprietary accounting software on
the machine - The check came as a surprise to both of us)
I was offered 7 inch diameter 600' tape reels (1/2 inch), fully
reconditioned (cleaned and actually recertified) for $6.25 per tape. I was
thinking of picking up some. I really like the small reels, normal size
reels are great for backup, but for OS load tapes and file transport I like
the 7 inchers.
A) Is this a good price?
B) Anyone want me to order some for them? (obviously depends on A)
