    Donation request: We have so many large format manuals to scan. It would only be possible with a large scale scanner. Such as a DS-70000 or something else that could scan 11.5x100 paper. See email information below (be sure to include BAMA in the subject line).

Maintenance and Operators Manuals for the Racal-Dana Model 9904 Frequency Meter.
Compliments of an unknown contributor.

Full circuit diagram for the Racal-Dana 9904 counter timer. The circuit diagram included in the manual is incomplete. Part of IC5 is missing; there is a 10mm gap in the middle of the circuit. 
Compliments of Laurence Curnow.
