       I found Phil Karns (ka9q) cp/m code for NOS, his tcp/ip stack and clients (in sn all in one program). It has been on a well lnown retro site for some time, but not findsble via web search somehow, and its not just me not searching well. Which is a separate story. Its written in C, eith the Aztec compiler (very nice tool). It sll compiles. It has as serious hardware integration with the Zilog SIO and Timer in a Xerox 820 that would need adaptation, but thats acreaons le project. Without the actual SIO chip there would be no HDLC and attendant functions but in 2026, no loss. Doesnt compile under MP/M -- not enough memory. NOS is pushing things. Its clean snd readable code. The Little Garden ISP ran on the DOS version of NOS, we pushed it hard, it had few problems. As a router, with four modems, we hung four customers each full /24 subnet,  on one low end single floppy DOS box feeding w router to the net. We called it "nail up" as opposed to dial up; stsy connected round the clock.Im not gonna pursue it at this time, ive got other things to do first. If someone here had the skills, and would bring it up, id provide them with a free fZ80 machine in exchange.... The partially prepped software bundle will be downloadable tomorrow. With compiler. Dev on CP/M is rough, you should know thet before you start.... MP/M is almost a joy. But since the task is narrow the device driver -- which will be firmware in thr Teensy 4.1 therefore gcc -- could be tested in an easy standalone program under MP/M which would be kinda fun and not gruelling at all. I'd help with that.
