Was handed a bag with about fifty 48 pin ceramic DIP Motorola chips. Date codes from 84 to 87. I think they may be house numbered 68008s but am not sure. The only part number that is consistent on all the chips are 50238 (with either a -01 or -05 suffix). Anyone have any thoughts on where to trace these down? Was also handed a fairly large bag of Z80 bits. Including Z80A, Z80B and a handful of Z80SIO Thanks, Kelly
