Anyone know where to get NMC9306s? It's an
incredibly old and terrible chip, so it's not currently manufactured, and Jameco
doesn't have any old pulls. Can't find them on any arcade repair parts sites,
either, which is usually my best bet. Anyone else have any usual sites for finding
vintage ICs?
Before anyone calls me out as a dummy: yes, a 93C06 should probably work fine (unless
someone can think of a reason they wouldn't). They're still not easily available,
but worst case, I can probably modify the few constants in the ROM which determine the
address length and modify it to work with a 93C46, which is still available. If that
turns out to be the case, I'll gladly release a patch.
