Yep, XT class machines didn't have a TOY CLOCK (TOY is time of year), All
the had was a periodic timer interrupt and when you power off so goes
the date. Hence the stuff like smart watch.
A multi-io card was typically 2 serial, joy stick. either a FDC interface.
Most were commonly two serial on one card, a Video and Parallel on another
with FDC being stand alone or paired up with the HDC. Clocks were commonly
the smart scoket under the bios roms.
I have many examples of those here.

I still have friends inside. The subtle point being I used to work there
and make a point of keeping in touch with the activities of what's left
of the old DEC. Also I didn't say making, I said selling.
I believe there is little if any VAX chip production going on.

Nit picking crap again. I was a Digit when it was ported to Alpha. While
nt and Unix was more or less new to alpha I was running a Jenson (early
alpha) on my desk and using VMS.
Keep in mind I run VAXen, talk to Digits (now Compaq) and live local to the

This building is about a 20 minute drive from my house. It's on Pulaski
Road in Greenlawn. The sign outside now says "GEC/Marconi/Hazeltine" and is
locally acknowledged as a Superfund site (although I never checked if it
made the CERCLA list or not). Place has been there forever and is a pretty
unassuming 2-story Government-style office building, but with no fences or
razor wire. Looking in, it appears that the interior consists of a cube-farm
on the lower floor and some offices on the upper floor. I don't know if
there is manufacturing in the rear or not, although it appears overall to be
a large building.

Attention, would-be rescuers in or near Milwaukee, WI! There's a
graduating student (Josh Hulbert) looking to get rid of a VAXen and PDP-11
(unknown model) as freebies.
If interested, contact him directly. Best of luck!

Hello All,
I will be graduating at the end of this quarter and moving several hundred
miles away from my dorm, so I need to minimize the amount of stuff I take
with me. I have the following VAX-related equipment, free for the taking:
VS2000, with VR-160-DA, LK201, and puck-mouse. I have the 3-meter long
cable for this one. It has an RD-54, and a RAM expansion to 20MB IIRC. I
know it boots and runs NetBSD just fine, but there is nothing on the RD54.
PDP-11: I know next to nothing about this thing. I picked it up for $10
at American Science and Surplus. From what I could gather, it may have
been a terminal server or something. It doesn't have enough RAM to load
an OS, but it has some funky ROM card. If anyone is interested, I can
send the M-numbers on the cards in the cage.
Heres the catch: You have to come get it, as shipping would exceed the
value of these boxes. I live in downtown Milwaukee, Wisconsin (USA).
Again, if anyone is interested, I can send part numbers on all the parts.

Didn't all the lead technicians who built NT come from DEC? In fact wasn't Dave Cutler, NT head honcho, the designer of VMS?

<question: Is there any classic operating system known for which the

Well if you took the time to look and read... This is a non exhaustive list
of just a few.
CPM (8080, z80, 8086, 68000) This also includes all of the CP/M
clones such as P2dos, Suprbdos, Zrdos, Zsdos. These can be
found at various FTP sites on the net.
Uzi Unix (z80, z180, z280)
Can be fount as www.psyber.com/~TCJ and also several other
versions at FTP sites.
Minix (808x, 80x86 and others) the book Operating System Design and
Implmentation ISBN 0-13-6386677-6 By Tanenbaum and Woodhull.
Also the sources and executables are on the net. Pretty good
simplified unix like OS that is source available for teaching and
other student/research use.
Classic Unix is available with a lowcost license (versions include
V5, 6, 7 and a whole load more.
RTS-8, OS/8 (also OS278) for PDP-8 family are at various places on the net.
This OS is good for illustrating the close relationship of hardware
to software.

Sure 'nuff. The original configuration of the IBM PC had no drives, and 4k
of memory. Diagnostics and a utility or two on Cassette (altho the
cassette player was optional?!?). BASIC in the ROM so it could be
programmed...
Back in the days when a single floppy drive and controller was a (apx. $900
option)
Frighteningly enough... I remember selling quite a few of them in that
(cassette only) configuration.

After searching for hours, i finally found out what cable this is. It connects
the 4869 external floppy to the P70 suitcase PS/2. Not of any use to anyone
who doesnt own those two items.

#5 was the battery-backed-up real-time clock, and I have this vague
recollection that #6 was something not directly on the card but
software which used the card, something like a RAMdisk driver.
