CGRS 6502 card for Altair bus

I've got a bare S100 board labeled "CGRS 6502 Computer Board, Rev A 7/77
WMS". The only reference I can find to CGRS is in the What's New column
of Byte 2:7(115)- July, 1977 - "A New Microcomputer Series from CGRS"
which describes three boards in the 6000 Series of Altair bus compatible
cards based on the MOS 6502 processor. Manufacturer is listed as CGRS
Microtech of Southhampton, PA.

Other refs to CGRS Microtech point to Commodore PET products including
RAM upgrades and an S100 interface card.

Anyone know anything more?
