Had to rescue the Nicolet computer. Still not sure if I'm going to keep
it...but at least it won't go to the scrap heap.
I've never seen core quite like this. Each core plane is 4 cards, about 4"
by 4", with 1K on each card (4k per core module) - plus the standard
xydriver and sense/inhibit. The four cards of the core assembly are joined
by small pins/solder brides between the cards. Really large doughnuts :-)
This machine is actually very clean inside, despite it's 1974 vintage.
The back panel is unique, with most peripheral devices connecting via coax.
There appears to be a home-brew mod to switch select tty (current loop) or
RS232 and if RS232 either 300 or 2400 baud.
Despite the grainy photo - the 8" floppy unit really has only one drive.
Also got the decitek paper tape unit.
If anyone is curious - pics attached.

Please, no attachments!
Give a address to website if anyone is insterested to look at it.
Some users on List have very limited resources and some dial in
by the minute pay or by hour. $$$.
Sheesh, not everybody have a cablemodem, 56Kps, and fancy
stuff. Some actually chose not to for good reasons which I
appreciate.

I agree completely. As it happens, I have a T1 at work, a 384K DSL at
home, and "fancy stuff". And I *STILL* don't want attachments.
Personally, if I were running the mailing list, I'd install a filter that
would *reject* any postings that contained MIME or uuencoded stuff.
If you have files to share with us, please just put them on a web or
FTP server, or mail them out on request only.
Thanks!

Well if you decide to pass it on please consider me first :)

Yes, I call it a core "sandwich". I've got photos of each card on my
Nicolet web site (still unfinished so no URL yet). The Nicolet computer
could have up to 12K of core, and I have the Expansion Chassis which
allows up to 24K more of memory (mine has 12K in the main CPU and 8K
installed in the expansion chassis).
The back panel is unique, with most peripheral devices
connecting via coax.
There appears to be a home-brew mod to switch select tty (current loop) or
RS232 and if RS232 either 300 or 2400 baud.
Actually, the peripherals connect into the two very wide bus slots on the
back; one is used to connect to the expansion chassis and ton mine the
other goes off to a Diablo 30 removable hard disk system. The coax
connectors go off to various subsystems that could be connected to the
CPU. For instance, my Nicolet computer is contained within a larger
desk-sized unit that includes an X-Y display (basically an oscilloscope),
flat bed plotter and fast fourier transform unit.

Nicolet is still around. I've been there, rescuing old junk.
I'll send a message to my friend there, and ask if there's an
old-timer who'd like to volunteer to record the details of the old
machines for posterity.
