I am allocating TimerB or TimerA(if B is unavailable) of CIAB and
would like to know the correct way to find out if the clock is
.709379Mhz PAL
or .715909Mhz NTSC
Thanks in advance,

When running under 1.3 and previous, determine the configuration (PAL/NTSC) of the machine by looking in GfxBase->foo (I don't remember, look it up). NOTE: Some Amigas (A3000s and the like) have a jumper to indicate to graphics the PAL/NTSC state of the machine; this jumper does NOT affect the EClock frequency, only what we ASSUME it is. rsbx ------------------------------------------------------------------------ Raymond S.
