Z80 Emulator for the PC
In the webmaster's opinion, there is only one Z-80 emulator you should use on your PC: MYZ80. Written seemingly eons ago, Simeon Cran's emulator has stood the test of time:

    *  supports all documented and undocumented Z-80 instructions
    *  extremely fast highly optimized emulation
    *  very slick interface to the IBM PC that allow anyone to add O/S extensions easily
    *  precisely and correctly handles CP/M disks (via a single PC file per CP/M disk)
    *  easy to substitute any operating system or BIOS

My goal was to have two MYZ80 downloads available here: Simeon Cran's MYZ80 in its original ZIP format and our expanded version that comes preconfigured with QP/M and some other Z-80 programs MICROCode Consulting wrote during that period.  Unfortunately, I have been unable to reach Simeon Cran to get permisiion, so instead I included:

    *  Simeon Cran's original MYZ80 package, unaltered
    *  QP/M package for MYZ80 that includes instructions (QPMNOTE.TXT), two different MYZ80 boot files for QP/M, and the QP/M Z-80 files in QPMFILES.LBR so you can easily configure MYZ80 for QP/M.  (You will also need to download NULU.COM to extract files from the library.)

In addition, a set of programs for manipulating .LBR files on the PC, which was handled by NULU.COM and was the "ZIP" of its time for the Z80, is also provided.  Enjoy!
