Logic regulator is missing from both systems, yes. Memory regulator is missing from the C.
One arithmetic logic card is missing from one system- but they should be pretty
interchangeable. So I have a full set for one running system.
With the logic regulator card, the B would be functionally complete. Thanks for the
schematic. I've started transporting the manual scans into a PCB design tool should it
become necessary to get a new board fabricated. I'd much prefer to find an original
though!

Hi all,
Returning to the occasional saga of the HP 2116 restoration.... It
appears the board which is most conspicuous by its absence is the
PSU logic supply regulator 2116-6014. Would anyone have one of
these available? Or failing that can anyone provide detail
photographs of an example?
I believe this board is nearly identical (or is identical) for the
2116B & 2116C - is it missing from both units that you have there?
I will send the schematics for the 2116C power supply, 2116B PS
schematic is available in the 2116B manual on bitsavers. Will take
photos of the 2116C board if you like.
Powered up my 2116C for the first time in a long while, after your
last message, and toggled in some blinkenlight programs. Still works,
at least.
