Looks like the 74S387 is another cross. Jameco has them for $4 each.

Most of these bipolar PROMs had many 'crosses', but for reading only. The programming methods are manufacturer-specific. Once programmed, the chips behave identically, so the PDP8/a (or watherver) doesn't care. So make sure whatever programmer you use can program the particular chip you are getting, and not just one that's a cross for it. Then you shoupd have no problems. -tony
