Notes

PCB is marked: "UG" on component side
There are a number of hand made modifications: most notably the 12x EPROMs TMS2532 are stacked in 6x pairs one over the other.
Pairs are: 1-5, 2-6, 3-7, 4-8, 10-11, 12-13
All the pairs have pin 20 of the bottom EPROM connected with tiny wires to some TTLs as per following table:

Pair  -> TTL       (pin)(location)
1-5   -> SN74LS139 (@12) (7b)
2-6   -> SN74LS139 (@11) (7b)
3-7   -> SN74LS139 (@10) (7b)
4-8   -> SN74LS139 (@09) (7b)
10-11 -> SN74SL00N (@09) (2s)
12-13 -> SN74SL00N (@09) (2s)
