Need a manual for the Berkeley Nucleonics (BNC) model 7010 digital delay generator. Single pcb with ovenised 10MHz crystal reference and series of dividers and programmable counters to generate accurate period and delays. Around 1970 vintage. Doesn't work on all ranges and suspect some of the counter chips are duff. Just need a schematic to save having to reverse engineer the whole thing. Any ideas ?, as nothing found on the on the web and BNC won't help...
