It does, The part is
39SF020 90-4C-PH 991391-A
I think the SST part is some internel lookup on their own catalog

What would the order code be for a flashable one? I don't have access to
Farnell's catalog but the store in college does so they can probably get
it for me. I've also managed to get access to a few EEPROM programmers at
this stage. All I need is that chip.

I trawled on usenet asking more or less the same thing. Most ppl were told
to fuck off. One managed to get a chip of them but it took two months and
cost him 40 dollars.
