Another bunch of chips that has been in the spare parts drawers for yonks! I can see the legs of all but one remain nice and shiny, the Fairchild legs do appear more dull. All legs are straight and are perfectly serviceable.
All SRAM has always been sitting embedded in the ESD foam (CMOS architecture) while awaiting a piece of equipment that is suffering from dementia! (memory issues)
