[comp.sys.amiga.tech] 2620/2630 Speed

Hi Dave,
With regards your statement that there might be a way to alter the PAL
setup to support different CPU/RAM speeds; does that mean that there
could conceivably be a way to utilize a 25 or 33 Mhz '020 on a 2620 ??
Just a thought.

Unfortunately no.  The A2620 is a synchronous accelerator; everything's 
based on a multiple of the Amiga system clocks, so you're fixed at
14.3 MHz.  The A2630, on the other hand, has CPU and memory based on
a private clock that has nothing to do with the Amiga system clocks.
While the shipped system is tuned for operation at 25MHz, there's no
designed-in requirement for 25MHz.
