Hi Mike,
Welcome back to the list.
I also collect older 8-bit micro's, mostly pre DOS machines.
I also don't have any experiance in the mainframe computers, with
the exception of my old ENIAC tube computer in my garage. (Grin)!
Would be interested in seeing your list of machines.
email is philclayton(a)mindspring.com
I have about 25 home computers, and another 25 or so business
based microcomputers in my collection..
CP/M based computers are my favorites..
Phil..
I know its off-topic but i figured that since most of the poeple on this
list work or have worked on the really big stuff you'd know better than
most others.
Say someone were to home-build a CPU from scratch using only individual
components, no ICs only modern descrete(?) components. How big would the
CPU be? For comparison lets say it would be an 8080 clone. Any guesses?

This is sort of a test, and a re-hello. I used to subscribe to this list
about a year ago. Hi. I've got more stuff. I concentrate mostly on old
8-bit computer systems. I recall some guys liking old mainframes. I don't
have that kind of space and that's not my background. Anyway. Hi!

I was wondering if anyone uses the Pascal compiler on the PDP-8, or if
anyone actively writes code that uses the Floating Point hardware?
One of these days I really need to scan a bunch of documentation in
on those two topics... Any suggestion for a good way to do that,
possibly with a pointer to some useful software on the web that I can
download...

I have a line on at least a couple if not more PDP11/73's in the UK. They
should
have at least the following BA23, M8190,1 or 2 meg memory, TK50, M7546, M7555,
RD53 or RD54. There are a few other boards in them I am VERY interested in that
I am prepared to buy the systems just for those other boards. If there is
anyone in the London area please contact me off list. ( or willing to make a
trip to
London area ) At least the above mentioned items will be yours for your
trouble.
The systems have RSX11M+ loaded I don't know yet if any have DECnet at this
time.
They will be scrapped if I don't buy them. If I buy them I will not pay to have
the entire systems shipped to the states so I am offering them to the list
members as basic systems. (I want the VSV21's and other goodies.:)
Please include your phone # and when is a good time to call so I can call to
discuss details. Please give me your time - I am very used to figuring the 5
hour difference.
Thanks
Dan
Dan,
I pretty sure I have in a large box of software a fresh copy of DesqView..
If you still need this let me know, and I will dig the stuff out to see..

Hi All,
Just got back from another scrounging trip. I picked up a PDP 11/05. Can
anyone give me a URL to a FAQ on these or tell me more about them and where
I can look up the card numbers? I know next to nothing about PDPs but this
one headed for the metal recyclers so I grabbed it.
While I was there I found a MEI wire bonder. This is a machine that
automaticly attachs the wire leads to the wafers in ICs. This one has been
sitting out in the weather and is ruined for it's intended use. It does
have a PDP 11/23 in it though. I'm wondering about picking it for the
computer and misc parts. Are the 11/23s worth anything? There's some other
very interesting stuff in the machine like a video camera and a video
recognition system but I doubt it would be possible to transplant that into
something else without a good set of technical info. Comments?

As the subject indicates, I'm in need of information on the 3400A,
specifically the Illustration Booklet with Schematic fold-out that is
referred to in the manual. Also, there was a 3400A up for sale on ebay
a while back, including a peripheral expansion system. I've already
done an exhaustive search on ebay but came up with nothing, ebay only
keeps record of auctions within the past 2 months. Does anyone have any
information about this expansion system? I'd like to try to build one.

I am just starting to go through the software I got with the 8/s and I don't
know what some of these older tapes did:
5/8-9 [(PDP 5/8) - Tape #9] - Analysis of Variance
5/8-15 - A.T.E.P.O. Program
5/8-45 - Remote Time Shared III System
5/8-54 - Tic Tac Toe Learning Program (figured this one out)
8/8s -77 - Dual Process Sys.
Some of these I can tell what they did by the name but does anyone have any
information about any of them? (I haven't had time to go through all the
documentation yet).
Thanks

Cool idea. I was going to do it the hard way.

Thanks, Kevin. Your enthusiastic efforts have saved me quite a bit of
time. The code looks OK, suggesting that I didn't post any typos, but
the possibility exists.
I only recognize (by octal address) certain, common disk interfaces (RL11,
RK611, etc.) Can anyone suggest what this might be a bootstrap to?
