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.
