Collectables?

[Chuck Guzis]

I just found an unused bare S-100 backplane PCB marked "EXP-4 Rev. 2" and
"(C) 1975, IMS Assoc. Inc.".  I'm assuming that it's for the IMSAI 8080,
but am not certain.

I've also discovered a bare Polymorphic Systems backplane from about the
same time.  I'll throw in the 4 edge connectors that were taped to it.  It
has pads for rectifiers, caps and what looks like a regulator on it.  

Let me know if you're interested.

Cheers,
Chuck
