I.e. no component values different than a regular 12" PET? Don't tell anyone, but if the monitor in a 12" PET is able to sync on both 15kHz and about 20kHz without needing readjustment we might get our monitors robbed off by vintage PC enthusiasts looking for a way to use their EGA boards :) Btw if you would want greyscales you could probably just copy the circuit from any monochrome analogue monitor or B/W TV set. I would actually had suggested using the electronics from some B/W monitor or TV set, but that was assuming that the 20kHz 12" PET monitor wouldn't work with 15kHz. -- (\_/) Copy the bunny to your mails to help (O.o) him achieve world domination.
