Features

• The main component is just a Pico2, and it's fast (Z80 10MHz/MC68000 12MHz operation, no wait states required!).
• This is exclusively for Raspberry Pi Pico2 (RP2350), not for Pico (RP2040).
• Pico2 (3.3V power supply) is directly connected to a Z80/MC68000-based SBC (5V power supply).
• ROM emulation is 8kByte, ROM-BASIC (Super AKI-80 only).
• Features reset output (open collector), clock output 20/12/10MHz, UART-USB conversion, and power supply (5V) function.
• Super AKI-80 can be operated with this one unit with minimal parts and no modification.
• This is an experimental project that also serves as training for RP2350's PIO, multi-core, UART-USB conversion, GPIO, etc.
