I have a hobby project with an old CP/M-80 system where the monochrome monitor is showing its age as the image is flickering a lot. I was wondering if I could attach a modern monitor or tv-screen, but I am not sure what standard the signal is called today.
I found this page describing the monitor characteristics (as far as I can tell from https://datamuseum.dk/bits/30001066 an adapted version of a NEC JB-1201M(A)), which says
- 50 Hz frame frequency.
- 275 active scan lines
- 33 vertical blanking intervals
- 308 total scan lines
- 15.4 kHz line frequency ~= 65 microsecond line period time
Is this just simply 240p (which my game capture device will be able to understand when I get a BNC-RCA adapter cable) or is it called something else?
