Hi there, > Do we have > to do timing like we do for the 2600? For instance, the NTSC 2600 > refreshes at ~60 frames per second and the PAL refreshes ~50 frames per > second. So if we wanted a some what acurate time clock we could take the > frame count (updated each new frame) and see if it were divisible by 60 or > 50 (or close enough to it). Would we have to do the same with the 7800? Where is the retraction when you need it? I can't believe I asked this question :-( Sorry guys...of course PAL would refresh at 50Hz. @Matthias Thanks for the CPU info. Take care, Dennis
