HP has all documentation online for these machines.

pretty impressive. this machine was first released in 1966 !!!!! ir was finally discontinued in 2000.
i don't know of any other computer that was made for such a long timespan.
Thanks for the links. I _thought_ I had the schematics for the power supply, but when I checked last night it turns out the files I have don't cover up to the 2113E. And the supply is quite different. So it's back to the hunt. You've probably saved me a lot of trouble, since last time I looked at the HP sites (long ago) they didn't have much at all. And what they had scanned was truly terrible, quality - mostly unusable. So I'd probably have looked there last.
Another one I found:
http://www.classiccmp.org/HP/These were workhorses. Many a chip tester used these beasts.
Coincidentally, I've also recently been collecting HP 8180A/1A/2A Data generator & analyzer sets, precisely so I can do driven-timing analysis of systems, including chips. That's going to be another teardown, sometime after I'm done with the HP 1000. The 818x machines are impressive beasts. Quite cheap now since they all have NiCad battery rot and a few other problems. But repairable.
AND I managed to get full service, op and programming manuals for all of them.
Not even contemplating using the HP 1000 to run them though. Will be HP-IB from standard PCs.
A computer history museum might want it when it's restored... have you tried asking around?
Ha ha ha! This is Australia. There is no 'around' to ask. I was hoping that this thread might come to the attention of potentially interested persons. Also posted on
http://www.vintage-computer.com but posts there show up only at moderator approval, and it's slow like treacle.
The biggest risk is that I'll get so attached to the machine while getting it going, that I won't want to sell it. In which case it would get put on a stand in my study and gather dust there, rather than taking up space and gathering dust in the workshop.
Based on some info I found it looks like the logic is not TTL but some ECL variant (hence the negative supply voltage):

http://www.cs.ubc.ca/~hilpert/e/HP21xx/CTL.html
I only have schematics and parts lists for the M series, not the 2113E/F. So far. The M series CPU board seems to be all 74xxx families logic: 74, 74H, 74S, etc.
But the E series is apparently faster, and I agree the -2V says 'ECL or something like it'.
Maybe that's where the 'E' in E-series came from? The 'F' stands for floating point - it's a E-series with an additional floating point microcode ROM set.
If anyone knows a url for 2113E/F power supply and CPU schematics, I'd really appreciate it.
Earlier ones from
http://bitsavers.trailing-edge.com/pdf/hp/1000/1000_MEF_EngrRefThis is all sort-of from one document, printed June 1979. Covers up to 2113A. Not 2113E/F
Only some sections are from later editions. Still no 2113E/F.
