Evaluation Boards

The JM-31 single board computer uses the popular 80C31 microcontroller, which has 128 bytes of internal RAM, tow 16-bit timer/counters, and five source interrupt structure. The JM-31 SBC, measuring 4"x5", provides up to 32K ROM (socked 27256 EPROM) and 32K RAM of system memory.

JM-552 Development Training System

The JM-552 Development Training System is a single board microcontroller development system designed around the 80C552 CMOS microcontroller. This chip is an enhanced derivative of the 8051 type processor. The system is designed to work as a stand-alone system or with the UMPS (Universal MicroProcessor Simulator/Debugger), a software development tool.
