Ah, OK. But, IIRC, there is a very subtle difference
between
the Zilog parts and the Mostek's. But, I'm sure it was in some
There's also a subtle (?) difference between 2 of the Japanese clones of
the Z80 (Toshiba and ???). The Epson PX8 (and I think the PX4) has a link
that you set one way for a Toshiba CPU and the other way for the other
brand. I'll have to check just what that link does.
No, *that* distinction goes to the bozos at TI with their
non-2732, 2732 (IIRC). So, if you wanted what the rest of
the world called a 2732, you had to order a 2532! (IIRC, 3
power supplies on their 2732..?)
You're thinking of the 2516. TI's 2716 was a 3-rail (+5V, +12V, -5V)
part, everybody else's was single rail. TI then made a single-rail 2K
EPROM and called it the 2516, it was much the same as everybody else's
2716...
AFAIK there never was a 3-rail 4K EPROM (2732-ish). The 2532 had
different pinouts fromthe 2732.
