I have a chance to buy an IBM 5160 (pc-xt) with I believe an original CGA
(iirc) monitor. The interesting thing is that he seller claims it has a
386-16 upgrade board. What do we know about these? How much would that
upgrade board be worth? I'm trying to figure out if his price is fair.

Thanks to help from the list admin, I have figured out why I stopped
seeing my own posts to the list!
Seems that gmail, in the their infinite wisdom, decided that it would be
best for me if my own messages were shunted directly to 'archive' and
never appear in the incoming folder. There is no control or option that I
can find to turn this "feature" off. Subsequently, I've had to change my
list subscription to use my ISP's mail service and all is well again.
Talk about obnoxious! I'm starting to wonder if gmail isn't more trouble
than it's worth. On the good side: It's free and their spam filtering is
very effective. On the bad side: They silently drop most binary
attachments, both coming and going, with no consistent policy involved
that I've been able to determine. And now, this.

Any one have copies of the WD controller specifications for the PC/AT?? It
would be a WD1003 model probably the ?WAH version but any version would be
appreciated. The following is a list of some known versions
WD1002A-WX1: Half-slot PC XT, PC AT compatible Winchester controller (MFM).
WD1002-27X: RLL 2,7 half-slot PC XT, PC AT compatible Winchester controller.
WD1002A-27X: Half-slot PC XT compatible Winchester controller. RLL, SMT, no
jumper selection required.
WD1003-WAH: Winchester controller with PC AT compatible interface.
RLL 2,7 version available (-RAH).
WD1003S-WAH: Surface mount technology version of WD1003-WAH.
RLL 2,7 version available (-RAH).
WD1003-WA2: Winchester and floppy controller board with PC AT interface.
RLL 2,7 version available (-RA2).
WD1003A-WA2: PC XT form factor version of WD1003-WA2.
RLL 2,7 version available (-RA2).
The corresponding WD AT interface chips are probably the WD11C00C-22 and the
WD12C00A-22 -? copies of their specs would also be appreciated.? I happen to
have the WD11C00C-17 spec, which is the XT version.

Hi Chuck:
I would very much like to get copies of both the SR and SM booklets. If u
are willing, can we work out details off line? My email address:
t.gardner-AT-computer.org
FWIW, the WD1003V is the 1986 version of this line. I'm not sure exactly
which model shipped in the first PC/AT other than I am pretty sure it was of
the WD1003 family.

Afraid you might be right on that one, Rich. :-(

Correct.

Hmm. What would prevent it? After all DECnet already exists for TOPS-20.
Did XKL make such big, incompatible changes to T20 after they got it

I would definitely not hold it above Peter to fix it if it didn't work
for some reason. He has done things like that in the past.
The Toad-1 do have a node number allocated on HECnet anyway.

I sort of missed most of the discussion on the Kiel PDP10 but in going thru
some of the dialog I came across this quote from one postings:

I worked on the Memorex 660-1 which is the RP02.
The RP02 (Memorex) and RP03 (ISS) are really significant early hard disk
drives and I would hope the Computer History Museum would be interested in
samples of both.
Can someone give me some status - where have they gone and are any still
available for collecting? If any are available, I can then work with the
museum to arrange for collecting them. If they are not available, it would
still be great to know where they are for reference and possible future
collection.
