Thanks for the info! Missed that the several times I looked at that.

From what I can tell from a quick look at the datasheets, on the 68764 the
/E pin is both a low power mode pin and an output enable pin, while on the
68766 the /G
There's also the unusual, little known but readily available and
programmable TMS2564 (Vpp also 25V, alas); it (sort of) stayed with
the original ROM/EPROM pinouts when everyone else switched to the
JEDEC standard as more pins became needed.
It's a 28 pin 8K x 8 EPROM, but the upper 24 pins are
Gents, please be aware of the WSI 57C49 Eprom, 8Kx8 in a 24 pin DIP
It can go low as 25nS access time.
Note that addresslines A10,A11 and A12 are swapped, so the contents needs to be
moved accordingly.
I used the C program below to create replacements for some Tektronix 4052 ROMS

For programming Motorola EPROMs for the KDF-11B I had very good luck
building and using this programmer:

I have one board with MCM68766 and two boards with SCM90448

None of my programmers I have here, can do it.

I have an old Logical Devices Inc, Gangpro 8 with DIP sockets on it.
What package is this part? Is it compatible with anything more widely
known?

What is an SCM90448? Can you find a datasheet for that part? I cannot.
