Not liking Joan's attitude as a reason for using and not paying for her CP/M and Z80 emulation package sounds like a rather convenient justification for taking advantage and saving bucks. If you feel you can't use her stuff in good conscience, don't use it at all. That's like saying it's OK to rob banks because some of them invest in South Africa! Sheesh.

Actually version 3.10 of Z80MU is officially marked "public domain", so one can use it with a clear conscience. If you have a V20 chip, I posted to GENIE and SIMTEL20 a package in Turbo Pascal that emulates a CP/M environment. It goes to more trouble than many of the early emulators to get the calls right.. for example SD and DISK76 work correctly. I believe that there are some undocumented manipulations of fields in the FCB bu BDOS which are not handled, so the WORDSTAR install program, written before random i/o, manipulated these fields directly, and fails on my emulation. The package was distributed with source as V20BOOT. Clarence Wilkerson

She puts her shareware fees much too high for it to be with most shareware which goes from $15-~$90. Like I said in an earlier message, it isn't worth THAT much. If you consider unreasonably high shareware fees "not liking Joan's attitude", so be it. I consider her attitude as only partly why I wouldn't buy it. It's the unreasonably high shareware fee that she asks which is not convincing me not to buy it. I guess the reason yo find it a convenient reason is because it's so easily obtained. It's distributed on the "try-before-you-buy" basis that is shareware. Also, just wondering, did you yourself pay the $150 she asks for it? Or did you find out about how much she wants and then decide not to use it?

What's intriguing to me is that Z80MU *DOES* support the "set DMA" call perfectly well! Furthermore, every assembler and compiler and loader that we've come across works perfectly well under Z80MU. At least, they work perfectly well under LEGITIMATE copies of Z80MU. Is it possible that somebody is using a corrupted copy of Z80MU? That's the only logical explanation that I can think of. We have seen quite a few corrupted copies out there. Who knows how or why it happens, but that's the breaks of Electronic Distribution. Once you let it out, you can't control what happens to it. I'm setting the record straight because I own Z80MU. Not a copy of it. The *REAL* Z80MU that Joan Riff wrote for me 4 years ago and that I rewrote myself. That's how I know that a *REAL* copy supports CP/M 2.2 perfectly well, even down to redirecting hardware I/O port addresses to 16-bit IBM PC port addresses for you fanatics who *REALLY* want to run a CP/M version of KERMIT or whatever. Drop me a line. I'll be glad to help to identify legitimate copies of Z80MU 3.10 (the last public domain version) and Z80MU 5.2b (the current, commercial version). There are thousands of folks running *LOTS* of off-the-wall CP/M software with Z80MU, and just about everything works perfectly well for them. Gosh, maybe there *ARE* benefits to buying a legitimate copy... Bob Baumann Computerwise Consulting Services P.O. Box 813, McLean, VA 22101 (703) 450-7175
