download source code of zrp in matlab
ZRP/M is a CP/M 2.2 emulation system for IB/M PC's and compatibles. It's author died a number of years ago, and hs brother has released this code for general use, free of charge. He feels, and I agree, that it was too good an effort to waste it by letting it lay on a shelf.
It appears that ZRP/M began life as a disassembly of a then popular operating system. It was then severly hacked into what it is today. Most emulators today emulate both the 8080/Z80 instruction set, and CP/M 2.2. ZRP/M consists of a binary code emulator that can handle 8080, Z80, and Z280 binary code. This emulator then runs the ZRP/M operating system, which is written in 8080 assembly language.
Source code is available for part of the system. The utilities have been enhanced, and the source for them is not present. The source is present for the operating system itself, and a Z80 emulator. I don't believe that the included emulator source is th Z280 emulatior.
