I've got an old inventory control program we wrote in dBase II to run on our Cromemco CP/M machine. Now and then I need to look back into that inventory to find a supplier on a part for a product we used to make. Also, my Avocet 6800 assembler is run under Z80MU. I had to reassemble some 20 year old code to fix Y2K problems a few years ago. Ran it under Z80MU! As I recall, it was freeware from some company that explained it was "too good to keep to ourselves." It ran (and still does run) all the CP/M software I had. Had to use Modem 7 to move stuff from the 8 inch floppies over to the PC though...
