This is information that I have discovered which may be of use to someone else. It's a mismatch of equivalent components, sources for rare components and links for manuals and datasheets!

Colour = Open Collector, Colour = Tri-State (It is sometimes possible to use one in place of the other, it depends upon the circuitry around it)

I spent ages looking around for this sort of information, so thought I'd better stick it somewhere that I cannot lose it. If you have documents with any more information on eprom settings / speeds, please let me have a copy!

I have a Data IO 29A eprom programmer, mainly for three rail devices
(2708's etc), although it's also good for bipolar proms. I managed to get it working (with some help from Leopardcats
page - the serial lead does work OK on a 29A) I've decided to add the manuals
for the programmer and the Unipak 2 (DjVu format) and also a copy of the
Promlink software that I have which has been patched to work on 2ghz+ CPU's.
(Back in 1994 when the last version of promlink was released, they probably were
not expecting CPU's to get that fast!!)
Promlink 6.10 Programs (with Speed Patch)
If you know any more equivalents, or some unusual sources of spare parts, then let me know
