+Hardware notes (AS12):

+- PCB label 510-1083A01
-- 3*8KB ROM(TMM2764), 2*2KB RAM(HM6116)
+- R65C02P3 @ 3/3.57MHz (apparently the first few had a 3MHz CPU)

 - PCB label 510-1084B01
+- R65C02P4 @ 4MHz
+- 3*8KB ROM(TMM2764), 2*2KB RAM(HM6116)
 
 This is on the SC12B board, with enough modifications to support more leds and
 magnetic chess board sensors. See sc12.cpp for a more technical description.
 
+TODO:
+- is the initial AS12 3MHz version the same ROM as felega1? When it's configured
+  at 3MHz and the CPU divider set to 2, the pace is the same as fscc12a.
