All true. I was focusing on what could be plugged into a KM8A. I
haven't personally checked my old programmers to see which variants
they can burn, but we used to blow out hundreds of 6309s, so while I'd
be confident I have the equipment to burn 6301s, I'd have to check on
the 74S387s.

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