[sdiy] 2532 EEPROMs

[Tom McClintock]

Actually, the 2532 and a 2732 are identical in nature, aside from a
slightly different pinout. The 2532 was TI's directly upgradable path
for the 2716, but no other manufacturers followed it and instead used
the Intel 2732 pinout. The 2532 uses pin 21 as A11, keeping pin 20 and
18 as CS and PD. The TMS2716 was the triple supply EPROM. However, all
EPROM programers should be able to handle these. The 2708 is the one
EPROM many programmers won't touch. Given enough time, you could easily
modify the PCB to accept a 2732 in place of a 2532, or just make an
adapter board.
