Hi Tony, indeed this machine has a 98204B video board (intended to work with a 35721 monitor, which I don't have). I have not yet found the specs for its composite signal. I find many $20 converters/scalers for composite to VGA on amazon or ebay but I am not sure whether such a thing would work for me. Obviously they seem to work for many computer games (SNES, Nintendo) and for some hobby computers like C64, Amiga etc. (e.g. "RCA Composite AV S-Video to VGA Converter Box"). Next I see $50 devices like "Mini Composite RCA CVBS AV To HDMI Converter (Input: AV; Output: HDMI)" which may also be an option, but only seem to scale to a fixed HDMI resolution, which may be unsuitable for the HP-resolution of 512x400 (or 512x390?). Finally I see $200 converters/scalers which are a bit expensive just for trying to see whether they work (e.g. "Atlona AT-AVS100 Composite/S-Video to Component/VGA Scaler"). I have also contacted Jon from the HP-Museum to see what their solution is. Regards, Martin
