Thanks for the link. I just opened both of them (I didn?t take pictures, maybe later). The GRI is a factory 753. It is spotless inside, wired per spec. I made a 753 work-alike for my IMSAI with the Processor Technology Subsystem B board set: http://q7.neurotica.com/Oldtech/VCF-East2009/IMG_0561-L.jpg http://q7.neurotica.com/Oldtech/VCF-East2009/IMG_0562-L.jpg I can?t wait to check it out and replace my Frankenstein keyboard with it. The other keyboard contains a ?Cherry 026-0738 Art Rev. C? keyboard unit. It also has ?001-1085? on the board. The board has three ICs ?dead bugged? on the back of it with ?white wires? running all around, including to the I/O edge connector. I?m not familiar with this unit, I?m starting to look for schematics now. Bill S.

Hi Bill, They are both great looking period keyboards but I do particularly love the George Risk keyboard. It might not be a model 756 but I do have some documentation and hopefully it can help.

The first in a long while where I found anything interesting. In addition to buying a large box of 7400 and 4000 series chips, all with 1970's date codes, I got two vintage keyboards: http://wsudbrink.dyndns.org:8080/images/kb_pics/20181215_162104.jpg http://wsudbrink.dyndns.org:8080/images/kb_pics/20181215_162139.jpg The estate sale employees have no idea where the associated systems (if any) are. They did not see them during the sale preparation and have not sold them. I also got a manual and set of 8 inch floppies for "Unicorn Systems Software Tools For CP/M". Twenty floppies, all with factory labels, various libraries, utilities and documentation files. I have not made a careful study of them yet (I just got home with them an hour ago).
