happy new year to everyone.

down here it started nicely, with the Optima ion gauge tripped over the break.
It's controlled by an Edwards Active Gauge Model AIG-E-B2P E-Beam via PCPS.
PCB board charred around the area of IC1, 3 more resistors and a diode burned, can't figure out what the IC was (ST Microelectronics 77????) or the values for the resistors.

Unfortunately not the original Optima setup, hence I do not have schematics or wiring diagrams. 

Question is, has anyone one of these controllers sitting in a shelf and is willing to sell/let it go?
Or: has anyone schematics for this controller (apparently build in 1986)
Or: has anyone this or a similar model (e.g. 004847000, no PCSP port) and can send me a digital image of the area around IC1, center of the PCB assembly, the only LED sits there.

thank you very much,
cheers
Chris
