The schematic is available here:
http://www.murgatroid.com/t_and_m/hp-00105-6100-figs.pdf . It's also
available with circuit description & waveforms here:
http://www.kennethkuhn.com/hpmuseum/scans/hp5065a_part3.pdf on pages
93-101 (pdf pages - not document pages). However, this copy doesn't
show the schematic for the power supply board. I also see that document
page 8-54 is missing which might be the problem.

If you send me the schematic for the circuit in which its used I can

Perhaps, but given what it's replacing and what it's driving, is the

Yes, I have the same configuration. The part number for the
divider board is 05061-6165. The 10811 + daughter boards are used
in the 105B, 5061B Cesium, and the 5065A Rubidium. The circuit
loading problem is exactly the kind of issue I was expecting.
Thanks for the warning. I could probably resolve it by replacing
the existing 7474 with a 74HCT74, but I'd like to minimize the
amount of hacking I inflict upon the unit.

A 74AHCT74 would be a superior replacement.
