I also have a 720, but I never tested the graphics display up to now (I only use it via serial line). My 720 has a single board graphics card with three BNC connectors on it. Is this really a 24bit graphics or a 8bit graphics. The only thing I know, is that the resolution was used with 1280x1024 under HP-UX 9.05 (or similar...). One day I will carry up my 21" monitor and try the grpahics on this machine ! Christoph Steve Pacenka wrote: > > Greetings, > > I have a couple of 720's and a couple of 735's to rehabilitate.
