Hello,
Having recently acquired some 6100's (I know they're
lesser than the 6120), I thought I'd try a PDP-8
project (I remember seeing these, but never got to
play with one.)
Thanks,
Dave
I have quantities of the 6100 processor chip (new in tubes) and have
been wanting to do a project with them as well. I have located all
the datasheets for the family and also the info for the Intercept and
Intercept, Jr. computers, which use the 6100. The serious constraints
of the 6100 processor are the small memory map. But with it's static
CMOS design it's a cool 'breadboard' computer because you can clock it
down to zero hertz.
Just a followup on this, because someone requested further info in
email. I have put up my IM6100 related datasheet collection on some
personal webspace. These are scanned datasheets in PDF format, and
include the datasheets for the whole 61xx line of chips. Please feel
encouraged to download and mirror this info where you like. Also in the
web folder is the usermanual (schematics, etc.) for the Intercept Jr.
which is a Single Board computer made with the 6100.
The url is:

Please feel free to download and mirror these documents if you maintain
a web or ftp archive where this info would be of value. I cannot
permanently maintain these files on my personal webspace.
I continue to be interested in learning what anybody else has done with
the 6100 processor in a small breadboard-style design. I'm interested
enough to supply anybody interested in pursuing this project with me a
6100 chip (I have NOS tubes of them) at a nominal cost of a few dollars
plus shipping. I've been considering putting together some sort of a
starter kit with some of the parts.
