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 by 2x EPROMs each, one on top of 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)
Also, 4x ROMs 2114UCE are stacked in 2x pairs by 2x RAMs each, one on top of the other.
All pairs have pin 8 of the top RAM bent out and connected with tiny wires to some TTLs as per following table:
Pair -> TTL (pin)(location) 1-2 -> unmarked (08) (8l) 3-4 -> unmarked (08) (8l) The TTL @8l is made of 2x unmarked TTLs, stacked one on top of the other.
