The visible part number would appear to be the number for the raw circuit card and does not seem to be related to what is on it. All four RAM modules and the ROM module of the board I am looking at have the 5180-2912 part number on them as does a 4K plugin I have. Those signal lines are probably on the other side of the circuit card, different part number different layout I would guess. What does the back of the "FORTH" module look like does it look similar?
