- Can anyone describe how the a and b timers on the 8520's count when set to
- use 02 mode?
- The hardware reference manual (1.3) says that they count down at
- 1/10 of the clock rate or .715909 MHZ. This is on a stock 68000 machine
- running at 7.16 MHZ. At what rate does the timer count down in a 25MHZ
- A3000? Is it hardwired to work at the same .715909 MHZ, or does it count
- count down at 25MHZ/10 = 2.5 MHZ?

- thanks,

- dan.
