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.

Before we mount a full-scale Salem Witch hunt... allow me to say
that I have had many pleasant dealings with my friends on this list,
and other lists... the percentage of deals gone sour has been very
low. Andrew Carnegie said: "It is better to be occasionally
cheated, than forever suspicious.."
And I can confess that there a few Nice People here on Classicmp
to whom I have promised to send various items; the promise still
exists but I have flaked out so far. Sorry Eric, Dave, Megan, Ian,
.... :] (In my defense: absolutely *no money* is involved in these
deals, most I am even shipping myself. And packing. And lugging..)
If I have sent you money, and you cannot complete your end of it
for some reason... send me the money back. Or tell me *when* you
can complete the deal. Or offer me something else I might want. Or
at least **tell** me that the item(s) and my money are no longer
available, and why that is so. Shit happens....at least give me the
true info and let me see what I can do.
But disappearing with someone else's funds is.. theft. That's all.
Confess your sins! Con-feesss you sins!! con-fesss your siiiins!!!
Or we shall torture you wiiiithhhh... The COMFY CHAIR!!!!!

partially filled one of those racks. The 8008 (1972-3) and later the 8080
were part of my life as I was there on the edge pushing it.
I never put a "good old" or "bad old" sticker as that was where things
were and even then it was clear the target was a fast moving one.

Hi all,
thank you for the extensive replies. What I meant was
"available for a reasonable price", which is not more than a few
hundred $ in my mind, so the PUPS offering really appeals
to me most.
Thanks and regards

Yesterday's snow kept all but about 8 tailgaters from coming to the York
Springfest, resulting in a rather dissapointing show. I managed to get
an Apple IIe for $2, an IBM Model 25 for $5, and a bunch of manuals
(including some for the IBM System/36), but that was about it.
I got two copies of "IBM Maintenance Library - 3278 Display Station
Models 1,2,3,and 4 Maintenance Information". Anybody want the second one
($5 shipped), or wish to trade for it (intersted in books on interfacing
the Apple II)?
I also purchased a book called "Master Transistor/IC Substitution
Handbook. A GIANT one-stop, easy-to-use manual that gives you commonly
available replacements for over 80,000 U.S. and foreign tranistors and
ICs...plus basing diagrams." (c)1977, 517 pages. Looks like it could be
a useful reference, if the the replacement part numbers are still up to
date. If somebody _really_ has a use for this book, let me know.
