Tek CFG280 - PAL/GAL JEDEC Files for U702 & U707?

[Chris56000]

Hi!

I was reading:-

https://www.eevblog.com/forum/beginners/simple-analog-function-generator-design/msg1174548/#msg1174548

. . .and I was interested in the Tektronix CFG280 schematics referenced in this article, post no 31, page 2, and there's one stumbling box to trying it as a home project, namely there's two PAL/GAL's in it!

Schematics:-

Can anyone tell me if the PAL/GAL devices U202/U707 used in this is available as spares, or has anybody got one of these CFG280s and can possibly attempt to read their JEDEC files for me or suggest if dumps has been posted anywhere?
