The design and implementation of an inexpensive microprocessor development system for the Z-80 microprocessor

Abstract

The Radio Shack home computer system, TRS-80, configured with level II Basic ROM's, 16K of RAM, its expansion interface, a single disk drive and a line printer interface to the Teletype model 40 line printer is bring used as a microprocessor development aid for the Z-80 microprocessor. Basic language programs are resident on the mini-disk and are used to load, to store, to dump and to execute assembled assembly language programs.
