Like all Motorola processors that share lineage from the 6800, they use the von Neumann architecture as well as memory-mapped I/O.
The engine control unit (ECU) of the 14CUX system is run by a Motorola MC6803U4 8-bit microprocessor, which is an uncommon variant of the otherwise ubiquitous 6803.

At Oundle he learnt to program the school's Data General Nova 3 computer alongside a number of pupils, built a Motorola 6800 based microcomputer from scratch, designing and etching the printed circuit boards personally and then purchased and built a kit SWTPC 6800-based computer which was made available to the pupils.
