Sorbus Chipset
The Chipset CPU board is just an adapter for all 30 GPIO of the "RP2040 Purple Board" to be connected to all pins on the bus, so it can drive the 65C02 on the 65C02 CPU board.
The Chipset board can also to be hacked to be used as a controller for a 32x32 WS2812 LED Matrix display. The demo 1k LEDs Is No Limit has been implemented this way.
