Hi guys,
I have 8 "new" Chips from Signetics, they are labeled:
S7536
N8220B
and on the backside between the pins "8220".
Does anyone know what they do? My search with google and
in the 1976 Signetics Date Manual (from Bitsavers) wasn't helpful...
Thanx in advance,
Holm

If anyone wants any DEC gear brought up to wcfmw, please contact me off
list.
If anyone is driving out from the NJ area, I have a few pieces of audio
equipment I need to get transported to IL.
I also collect US and foreign coins and currency, and am interested in
buying or trading for DEC items.
Thanks, Paul
Classic computers have a value in our capitalist society. Take the Apple-1:
Its value can be in the $100,000s. One is for sale now: ~ $200,000. Next
seems to be the Kenbak-1 valued somewhere around $50,000. Now, I’m not
suggesting money is the epitome for evaluating our hobby but it goes a long
way to explaining its longevity.
Happy computing.
Murray 🙂
Add. I'm unable to get the output from your site but hope to contribute in
some small way.
I finally got an Emacs running on v7--it's on misspiggy at LCML now as "ue".
It's Microemacs 3.6; what I did was to clone
https://github.com/troglobit/MicroEMACS and check out the first commit.
Some experimentation later, it had the usual problem with v7 and DEC
linkers that not all the function names (er, more generally exported
symbols, but in this case, function names) were unique in the first 7
characters (which is 6 if you're working with DEC OSes). So a bit of sed
later and I had something that built, linked, and appears to run with
TERM=vt100 set.
Arrow keys, naturally, don't work, but C-b, C-f, C-p, C-n do.
I think I'm going to just make a GH repo of it, but I'm happy to send the
tarball, or tar.uue, upon request. I find UUCP kinda fragile on my simh
installation, and I don't know how to get to Miss Piggy's (although the
uucp commands are there), so, well, uuencoding, a pasteboard buffer,
iTerm2's "Paste Slowly", and cat will work as a file transfer mechanism.
Now I'm going to run over to TUHS and announce the same.

While I have a couple Apple ]['s I really don't do much with them. Haven't
even turned one on since I retired from the University in 2015 and they
came home .
Wouldn't take an Apple 1 as a gift but I, too, would love to have an IMSAI
and a SWTPC 6800.

I have heard rumors of one "fredmacs" which is a more-or-less emacs that
will run on PDP-11 v7 Unix. Since I've gotten "s" onto v7 and behaving
mostly happily, now I'd like an editor I actually _like_ rather than
_tolerate_.
Does anyone know where to find the fredmacs sources?

Hi all,
I just came across pictures on the LCM website about their SDS Sigma installation there.
On the pictures, one can see 10-platter disk packs in the corner and stored on the disk drives.
Did the LCM ever had these in operation, either for data retrieval or even demo purposes?
I know of the Jim Austin Computer museum where they fixed a CDC 9766 drive but it suffered
a head crash after a few hours according to their description which led to giving up the operation
of these drives.
Greetings,
Pierre

Hi there
I recently had a mad hankering to add a SunPC card to my Sparcstation. A lot of you will be familiar with the SBUS cards with a 486 or '586' processor.
Does anyone have one spare they would like to part with? Please PM me if you do.
Anything really not at all fussed.
This sort of re-creates a setup I had as a post graduate when I had a new 486DX2 alongside a Sparcstation 2, or at least had access to them. Both were pretty amazing machines at the time.
I do remember benchmarking these two machines running similar C software I'd compiled up (a simple electromagnetic simulator), and it was noticeable that the sparcstation was at least twice as fast.
