README.TXT ---------- Y2K compliant TOD.PRL and SCHED.PRL Hector Peraza https://github.com/hperaza/P112-isx Hector has done substantial work uncovering both history and executable PL/M code and systems. Digital Research ran PL/M on an ISIS machine, not CP/M. But at some point DR created a specially modified CP/M system (BIOS and BDOS hacks, plus a wedge called ISX.COM) that allowed the ISIS PL/M compiler to run on "CP/M". It's a serious kludge, if it works as described fZ80 could be hacked to run it, I believe. But there are many unknowns, and I am not investing the efort to puzzle it all out. The work was done for a unique machine called the P112 (described in Wikipedia), but also for emulation under linux. There is a lot of information at the link above. But Hector fixed the Y2K problem of TOD.PRL and SCHED.PRL. TOD is not that important but SCHED.PRL is. --------------------
