- I believe the Falcon has a 24-bit address bus and a 32 bit data bus,
- while the 56001 has a 16 bit address bus, and a 24-bit data bus. The
- Falcon is a 32-bit computer with limited memory management.

-
- The adc/dac channel is driven off the DMA clock, which is driven off a
- sub-divided horizontal scan rate. The 525 scan line rate sub-divided
- by 12, 24, 48 and 96 give the 6250, 12500, 25000 and 50000 bytes per
- second DMA/CODEC rate. This is the same as the STE/TT.

- Just passing along what I've heard...
