[time-nuts] Re: Looking for HP 10811D manual (if such exists)

[Tom Van Baak]

Rick,

This 111-page PDF contains info on both the 10811 A/B and 10811 C/D, 
including schematics:

See especially pages 75 - 100 for details on all the variations.

Note the A and D models use the familiar hp 10544 compatible 15-pin edge 
connector while the B and E models use SMB and feedthrough connectors.
