The very first programmable logic (electronupdate.blogspot.com):
#Signetics brought out the 82S100 (later PLS100) programmable logic array in 01975. Decapped die photos. #electronics #hardware #history

82S100%20Fpga (deramp.com):
#PDF of the #datasheet for #Signetics’s 82S100 and 82S101 fuse-programmable logic array. Looks like a PLD: and/or/invert matrix with 16 inputs, 48 product terms, and 8 outputs. This version of the dadashit is from 01987 with parts from 01990, but I think the chip is from the 01970s. #electronics #hardware #history
