From the project
A trainer / demonstration system for the Motorola MC14500B
The Uno 14500 is a demonstration and training system built around the Motorola MC14500BCP Industrial Control Unit.
Its design borrows heavily from several sources including the Motorola ICU Handbook, Usagi Electric's MC14500 SBC, Nicola Cimmino's PLC14500, and my original Uno computer, a CMOS CPU I wire wrapped in college.
The system has 256 bytes of program memory, an 8 bit scratch register, an 8 bit output register, and an 8 bit input mux.
