The Microcomputer Training System by Integrated Computer Systems, Inc (around 1980) is a self-contained computer with keyboard and an eight-character display. The core of this system is an AMD 8080 microprocessor.
The computer board rests on a -5/-12/+5/+12 V powersupply. There are facilities for connecting additional memory and peripherals (like teletype, monitor, cassette tape recorder).
The accompanying book (part I) features a step-by-step course in assembly programming. An assembler is built in the system's read-only memory.
