I have been able to make the first screen of my dual playfield, and I have tried attaching the 2nd playfield myself, as was done in the demo program by Rob Peck, but nothing seems to happen. It MUST be working and doing something, as it s\goes through the functions, reports no errors, and cleans up OK with no memory holes, etc. But I still get only the first screen showing up. It is possible that it really IS doing it, but that it is not displaying the custom bit map that I have created for it. Is there some bit that I must set to tell it that the bit map already contains data? I did this for the first playfield and it worked fine. The 2nd screen just comes in black. After I have attached it to the first screen, but before I have called MakeScreen() and RethinkDisplay() I set the colors from 8-15 using SetRGB4(), and that also causes no error (setting colors 8-15 when each screen is only 3 bitplanes deep). Any ideas? Dave
