Sadly, the TIF you found does not seem to have the information, but thanks
for looking.
As for IRC, ychat wants to install Java and I don't. For the amount of use I
would get out of IRC I don't really want to pay for a commercial copy
either. If you can suggest an IRC client that runs on Windows, that is free
because I would not use it a lot, and doesn't want to install Java or scads
of Unix compatibility software (eg Cygwin) then I am all ears.
By the way, if I can I will come to the next steaming of the Leawood pump in
Cromford, it looks interesting and I think my sons would enjoy it.
Regards
Rob

Incidentally, a while back you responded to an email about the H7140
PSU from the PDP11/24, for which I think you also have the fiche. I am
still interested in a couple of bits of information from the printset
for the newer design, would you be able photograph a couple of pages?
I am interested in the Input Assembly and the Bias and Interface
board. On the latter I have a specific question: My bias and interface
board had what looked like a broken track, and it did look broken
rather than deliberately cut. Could you tell me if the collector of Q2
(p87 of the older printset on
bitsavers) is connected to anything? If so, what is it connected to?
Been trawling the fiche and net while I have the IPB docs for the
H7140 I dont seem to have the technical manual with the circuit so cannot
give any circuit details, the H7140 is not mentioned in the index part older docs on bitsavers seem to cover it
so after some digging I only find EK-BA11A-TM-003 that points to MP00832

Unfortunately I don't have IRC so we'll have to rely on email.

internet! therefore you have irc, just install xchat (linux) (windaz)
