Revision A hardware:
* TMS1000 (has internal ROM), DS75494 lamp driver
-
+
Newer revisions have a smaller 16-pin MB4850 chip instead of the TMS1000.
This one has been decapped too, but we couldn't find an internal ROM.
It is possibly a cost-reduced custom ASIC specifically for Simon.

Other games assumed to be on similar hardware:
- Pocket Simon, but there's a chance it only exists with MB4850 chip
- Super Simon (TMS1100)
