---snip--- Hi Sorry about that, this was intended for Chris only but if there is anyone else interested in getting the CP/M-8000 up and running, let me know. It may be easy but one can never tell. I'm not much of a C expert. I wish they'd just done it in assembly. Proper used of macros would have made the job easy enough. My main complaint is that it requires either a PDP-11 with their compiler or a working CP/M-8000. Of course, that is what I'm trying to create. Writing an assembler is relatively trivial while writing a C compiler is a bit more. There are several M*** assemblers that one could easily adapt to the 8000 out there as well ( I do tend to write my own though ). The stuff from the web site looks like one may be able to build a booting disk. I'll be working on that, over the next few days. Dwight
