What would be most benificial next is to remove some of the ICs
with the red dots to revel the part number that has been obscured.
Also the ICs that have reference # on them. Critical ones come to
mind is U55, U25 and U41. Also the two next to the EPROM
(CGROM). I believe those to be N82S series of TTL prom smade by
Philips and several other companies in the 80's.
I think once we have a complete knowledge of the part numbers on
all the ICs, some brainstorming can start to derive the individual ICs
into groups of ICs to do specific functions. We could be able to
derive what ICs form the 12 bit timer. The address generator for the
video.
I think we first need to estblish a list with all the IC part numbers.
just my thoughts
