I am interested in acquiring documentation, parts, and any other hardware related to the 14500 processor, especially any instructions specific to the DS 14500A ICU Demonstration Unit.
I did manage to find a development/demo kit that Motorola produced for
the MC14500B (the DS14500A Industrial Control Unit Demonstration System).
The MC14500 B industrial control unit (ICU) is a single bit CMOS processor. The ICU is designed for use in systems reqiring decisions based on successive single bit information. An external ROM stores the control program. With a program counter (and output latches and input multiplexers, if required) the ICU in a system forms a stored program controller that replaces combinatorial logic. Applications include relay logic processing, serial data manipulation and control. The ICU also may control an MPU or be controlled by an MPU.
- 16 instructions
- DC to 1.0 MHz operation at VDD = 5 V
- On chip clock (oscillator)
- Executes one instruction per clock cycle
- 3 V to 18 V operation
- 16 pins, DIP (14500 BCP) and CERDIP (14500 BCL)
