A friend of a friend has an old xenix machine; Compaq DeskPro 386
running Xenix. He shut if off after running for years and it won't
boot because the cmos battery is dead.
The disk is an ESDI drive attached to a Compaq ESDI/FLPY controller
(copyright 1989) ISA bus card.
He says can't see any way to enter a "setup" mode in the BIOS.
Anyone know how to fix this?
apparently it has his Alfa Romeo motor club data on it (so it's clearly
Anyone know if the xenix fs can be mounted on linux? (I doubt it, but
I thought I'd ask)

If you'd like it and are in the Columbus, OH area to pick it up, shoot me an
email! Highest offer gets it :)
I have been on a quest to obtain one of these. If you have one for sale
at non-bandit rates (see classcomputermuseum's auction for an example of
the latter), or know of one, please advise!

If you download the manual you will see that it is in color and was scanned at 300 dpi color. I believe that HP did this on purpose
so that you could not copy it on a copy machine but rather contact them and purchase another copy.
On the rom listing I had to even play with the contrast and brightness just to get it to be read. Please if you want take a crack
in reducing the file. As I spent the entire day just on the 40 pages it was the best I could do to get out the document for those
folks whom have the trainer without the manual when it came to the schematics those were scanned in black and white as they
are black and white.

So happens one of my "small" pdp-11s uses a Tu58. the system is a BA-11V
with an 11/23 256k of ram, DLV11J and MRV11 rom(boot). Takes 10 minutes
to boot, setup VM: then copy key files to and reboot. After that it's
pretty decent even if I have to access a file on tape.
Everytime I runs it with a bunch of kids of the current PC generations
they go gaga and comment on how slow then I explain the amount of ram and
storage then they are amazed it can be a functional machine with so little.
They can't imagine a useful machine with 32kW of ram and 256kb of storage.
On the flip side I've used that same Tu58 to bring up iron that had no
removable storage. It's slow but very dependable.
I just gotta get a Flexowriter. Who has one that will sell it to
me? I had one years ago and gave it up in time of crisis. (Yes, I
deserve it.) No reasonable asking price refused!

I'm looking for ND-100 information. A couple of my friends have started
to work on a ND-100 emulator and it is progressing fast... fast to a
point where we are lacking information about the inner workings of the

interrupt and micro code programming but other information (manuals,
schematics or programs) is also interesting.

The hardware we got access to is a ND-100 satellite, two ND-100 racks
with disks and 8 inch floppys in parts and a nonfunctional NORD-10 in a
rack. When time permits we will try to get it running.
I recently had two more items packed and delivered to me by Craters &
Freighters. Holy shit, what a difference it makes with that company.
A Tektronix 4170 local graphics processor and an Evans & Sutherland PS
390 base unit arrived with no scratches, no falling apart pallets and
The tally so far:
+ seller freight packed deskside SGI Onyx
+ C&F packed lot from dovebid (Tektronix graphics terminals)
+ C&F packed Megatek graphics terminal
+ C&F packed E&S PS390
+ C&F packed Tektronix 4170
- CTS packed deskside SGI Onyx & Octanes
- adcom worldwide packed SGI Octanes, O2s and monitors
In the case of CTS/adcom worldwide, the only reason that I used them
and not C&F is that there wasn't a C&F that could go to Reading, PA
and pick up the stuff from a dovebid auction.
C&F may not be the cheapest; to be honest, when C&F service is
available I don't even bother to check with other freight shipping
service companies. However, what good does it do you to save a few
dollars on shipping and have something arrive smashed or cosmetically
ruined because of poor packing?
I heartily recommend Craters & Freighters for your packing and freight

I have 3 SS20s and 4 SS10s. Mostly complete. All have one or more
processors (ranging from SM41 to SM61), I believe all have RAM,
and some have one or more drives. No GFX as these were last
used for servers.
These are free for pickup in Sharon, MA 02067, or I can bring
them with me to work in Cambridge, MA 02140 (on the same
road as Alewife T station).
If you want one shipped... $10 + actual ship with the $10 to
cover the materials/time to pack and haul to PO/FedEx/UPS/etc.
If these don't move before that dumpster leaves here (1-2 weeks
>from Friday), then I'll pull the CPUs, RAM, and drives, and heave
them into the dumpster.
The SS20s are all Aurora I chasis. I don't recall any having CD
rom drives... one or two fo the might have floppy drives.
