I have a pretty complete set of docs for the IBM PC/RT; the only thing I am
missing are the set of boot/install disks (I loaned them out for copying and
haven't gotten them back yet.) At some point, I'd like to get them to Al for
scanning ... in his copious spare time :).
If the CTOS is the same for the B20, Al should have those as I loaned him the
installation disks and docs to duplicate some time back.

do you have a working drive?
every one I know of has had the rubber roller go bad.
I have a copy of the unreleased driver with a number of bug fixes from the author.
I find that if I don't ask occasionally, I don't get anything....
So,
I'm looking for various software bits:
boot floppy or install media for Burroughs B26 or any idea how to break
the CTOS admin account
same for a Siemens-Nixdorf RM400-10
AIX and/or AOS install media for a PC/RT (those used to be on
ftp.dementia.org, but are no longer there, and I can't find my copy)
XENIX 386
Actual media or floppy/tape images; I don't care.
Documentation for all the above systems
Hardware bits:
mouse and/or color graphics for the PC/RT
keyboard for Mindset system (with some sort of return agreement; I have
no idea whether the box is alive or not)
I don't expect any of this for free.

Hey all,
I just missed out on a Tek 7904 scope (four trace) with four plug-ins for
$299. Was that a deal? The plugins were 7A26 7A18 7CTIN and 7B53A.
Looks like a 500mhz scope, but with plugins good for 200mhz and a curve
tracer.
Are plugins for that scope readily avaiable and reasonably priced?

A while back I posted that I had some fairly old XXDP+ library RL02 carts
and posted listings of the files on them.
Several people asked for copies of the images. I finally got around to
pulling them in via vtserver. You can get them at:
http://www.classiccmp.org/PDP-11/XXDP/
I also included listings of the directories.
Just out of curiousity, what's the best way to tell what version # of xxdp+
I have? I know the one labled 'Disk 8' comes up with CHMDLB0, while the one
labled 'olddiag' comes up with CHMDLE0. Can those be tied back to a
particular xxdp+ version?

HP 7970 drives look a LOT like Kennedy 9100's
Lots of others primarily in mainframes (STC,
Telex,...)
Those two drives in the pics are fairly old incremental
transports.
As difficult as it is to find information on vintage terminals, its
even harder to find information on vintage pen plotters. A pen
plotter was about the only form of graphical output you could expect
to see on a vintage graphics system as film recorders were very
expensive.
OK, what do you have in your collection(s)?

Wow Pax, very juicy and flavorful information. Thanks!
