Someone is auctioning tubes of harris 6100's on ebay:
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=4663&item=25…
Am I correct in thinking this is a pdp-8 compatible processor?
Can you build a pdp-8 clone like the sbc6120 using these?

Yes you can, but real PDP 8 I/O and memory over 4kw require other
support chips. Also since the chip is CMOS speed and output drive
is limited. Until you can get a data sheet on the devices it may
be wise to not get the chips. Intersel made the 6100's first I think.

I found a nice datasheet for the im6100 on pdp8.net, but nothing
on the 6102 or the other support chips.

The 6120 is also CMOS and look what Bob Armstrong has done with it.
DECmates run at 8MHz, not quite as fast as a PDP-8/a, but in the
ballpark. Much faster than a PDP-8/S :-)

They did, 1976. Also, the 6100 is used in the VT78 (one of the only
PDP-8 variants I _don't_ have), so I bought a tube too, in case I
ever get a VT78. I doubt I'll be able to find a single part for $15
shipped if go looking later, let alone 11. The 6120 goes for $50 new.

I happen to have the Intersil and harris
databooks for the 6100 and
support chips, if nobody has scanned them yet, I'll see if I can get to
it.

Ah, with the 6101, 6102, and 6103 datasheets as well,
it appears. Thank you!

The thanks should go to Bob Armstrong. After all the work he's done for us
regarding the SBC6120, I'm plugging him all I can!
