Z P M 3 by Simeon Cran ======================== A Z80 coded CP/M 3.0 compatible BDOS replacement. ZPM3 offers all the good things that CP/M 3.0 does, and then it offers more. Because ZPM3 is written in Z80 code rather than the 8080 code of CP/M 3.0, it can do everything that CP/M 3.0 does, but in much less space. With the extra space recovered, ZPM3 packs in a number of new facilities. Yet the whole package fits in exactly the same space as CP/M 3.0 so you can directly replace your old CP/M 3.0 BDOS with ZPM3 without a worry. ZPM3 is also fast. Faster, in fact, than CP/M 3.0. This is possible because the rich Z80 instruction set allows many algorithms to be implemented more efficiently. In addition, the extra space available in ZPM3 has been put to use to further optimise the code. Lots of small optimisations smooth the execution flow, so ZPM3 becomes the fastest operating system on most banked CP/M computers. ---------- This is version 1.0....... You do not need to compile a new CP/M system (like before..zpm v0.8) ! The makezpm utilities will work with CP/M on the C128.....! Most C128 users cannot generate a new system as no sys gen. utilities (eg., LINK, GENCPM, ADDBIOS, etc) were included with the original-factory CPM+.SYS system diskette.
