I have found two ways of writing PIC programs with Z80 like mnemonics. NEW in yaze-ag version 2. Harte's S-100 Archive. Note that my Z80 bus design is such that the "read" and "write" signals are only active when a particular card slot's I/O range is active, and so I don't have to decode anything besides A0 and A1. Z80 programming techniques - Loops. 0 Assembles Z80 microprocessor code into an object file and an Intel hex file for an EPROM programmer. Later it was superceded by IDE's such as Assembly Studio 8x and SPASM, however in some cases it is still used to this day. I tried adding a new item to list using WCF Service. There also exist some other useful ones, like "Z80 assembly language subroutines" by Lance A. Perhaps its best feature is that it is totally awesome. The Z80 microprocessor designed by Zilog powered some notable business PCs back in the mid 70's to early 80's, including the Osborne 1, Epsom QX-10 and the TRS-80 (among a host of others).
