“SticKey” – “sticks + keys” - Input controller (RT2350B), pronounced “Sticky”

CPU overclocked from (1x) 150Mhz (1.1v) to (2x) 300Mhz (1.2v), possibly to (3x) 460Mhz (1.5v) – other have driven the RP2350B to over 600Mhz (2v).

SticKey has no flash and no ps-ram, it's code is loaded into RAM from DeMon. The flash interface is used for FRAM access.

SticKey is an I/O controller that supports:

Four Atari/Sega DP9 stick ports, (6 button sticks, analog paddles, 9 pin mice). Port A can optionally be a HS TX connection. All ports are 5v logic.

Internal USB keyboard connector.
