==Notes==
PCB is marked: "UG" on component side<br>
There are a number of hand made modifications:<br>
most notably the 12x EPROMs TMS2532 are stacked in 6x pairs by 2x EPROMs each, one on top of the other.<br>
Pairs are: 1-5, 2-6, 3-7, 4-8, 10-11, 12-13<br>
All the pairs have pin 20 of the bottom EPROM connected with tiny wires to some TTLs as per following table:<br>
<pre>
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)
</pre>
<br>
Also, 4x RAMs 2114UCE are stacked in 2x pairs by 2x RAMs each, one on top of the other.<br>
All pairs have pin 8 of the top RAM bent out and connected with tiny wires to some TTLs as per following table:<br>
<pre>
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.
