Altair parts substitutions

Yeah . . . I remember those, too. Intel made essentially the same parts
with different numbers, apparently for marketing purposes. They had the
8708 and the 2758, both of which were 24-pin 8 k-bit EPROMs, similar pinout,
etc.

Several vendors were competing to see who could foul up the numbering scheme
the worst. I don't know who won.
