The hardware of the Sorbus computers could not be simpler. Designed with care to be as flexible as possible, fully programmable in behaviour, with a small footprint and at very low cost.
Two components: a 6502 CPU and the ‘purple’ RP20240 board.
The design is open source hard- and software. Have a look at the Sorbus github page for the details. All information here is based upon this.
The goal of the Sorbus system is to play with the 6502 as simple and affordable as possible. It can run many serial terminal based 6502 programs, such as the Apple 1 Wozmon monitor, or the TIM monitor with a system clock over 1 MHz or special programs to study the behaviour of the 6502, step by step at very low clock rates (with a 65C02, the CMOS variant is a static design)
The Sorbus computer is 6502 based, including the 65816. The RP2040 serves as fully programmable peripheral for clock, reset, NMI/IRQ, RAM, ROM, serial I/O.
