Propeller and CP/M: A perfect match.
Question: What does a Propeller chip have in common with this old machine?
Answer: They both can run Wordstar 4. (Well sort of)
I've been playing with a board called the N8VEM, a 6"x4" mini CP/M computer with a Z80 processor, powered by 5v. The N8VEM's output device is a standard serial port, this is where the Propeller chip comes in. I've been creating VT100 terminal software for the Propeller, translating all those old Vt100 codes into a window into the past.
Pictures of the project as it progresses can be found here. The Propeller PPDB board is compliments of Parallax, (Thank you Ken!) and the N8VEM board was compliments of James Moxham (Thank you James!)
This is a truely interesting project combining my love of Retrocomputing with modern microcontroller technology. Playing with CP/M 2.2, Wordstar, and BASIC-80 feels a little like being a technology archaeologist at a dig site.
