The TI TBP18SA030 is a 16 pin fusible link PROM.
32 X 8 bits.

Anybody got some suggestions on what I can use for a replacement?
The SN74S188 is supposed to be the same, but that doesn't solve
my problem.

I'm looking for something along the lines of 27C64 or such.
I don't mind making up a 16 -> 28 pin adapter.

Thanks
Jeff

it looks like still make it in extended temp rage in a ceramic case as
JBP18S030MJ. I wonder who still uses these or what they're fixing
with them.

74S288 by National Semi and 82S123 by Pilips and Signetics.

Make me rich and I'll send you the official bipolar PROM bag phone
programmer. Are you programming an MCX-90/100? There's also a
Standard low-band radio I have buried somewhere that uses this bipolar
PROM. You might ask on the Batlabs forum.

Well, just about any PAL with five inputs and eight outputs...

It's for a onesie? Maybe 28F64 would be easier than 27C64 to
program... neither is going to be as fast as the TBP18SA030
(about 30 ns, I think).
