VTG 1960/70's IBM RESEARCH GE LOGIC PC BOARD or IBM SMS CARD DATABASE ?
I found this board in my grandfather's basement. Sorry, my knowledge is very limited for this board which seems to have never been used. Please look at the images carefully before bidding. Sold as found and "as-is". No Reserve Auction. Happy Bidding!

An amazing member gave me this info about the board: This IBM double wide SMS card is a type TMA. Not sure of the function. I believe the 033 transistors are PNP and the 192 transistors are NPN. The transistor date codes seem to be 6336, or 1963 in 36th week of the year.
