Batboard

I have a IFR COM-120C on my Ham Radio test bench. I'm going to be replacing my failing RTC Dallas Watchdog DS1286 Timekeeper on my IFR-120C's Controller Tray PCBd. I understand from reviewing notes on other's post that their is some 120c data information stored in the NV Ram 50 bit area, like the ... Tracking Gen Option(s) and units S/N. Was looking to buy a Aeroflex Com-120C Maintenance Service Shop Manual on CD/DVD or in paperback form, so I'm able to re-enter my units S/N and options via the serial port, using a smart terminal program. What I DO NOT NEED, and already have a copy of, is the BLOCK DIAGRAM Maintenance Manual Supplement 1002-0601-4PO, which has NO information for what I'm trying to do.

Thanks;
