- I am interested in running the ARM3 in my A5000 at some slightly higher clock
- speed (we are not talking cooling units here!) I expect that someone out there
- has done some clock speed/performance experiments. eg, Acorn/ARM Ltd/Aleph One.
- and it would be interesting if these could be posted to the net.
-
- I have heard that it is quite reasonable to run most ARM3s at 30MHz (A5K runs
- at 25MHz, or it could be 24MHz), but I have had difficulty in finding the
- appropriate clock crystals at greater than 50MHz (you need *2). I have tried
- Maplin, RS & Farnell - could anyone suggest a source for higher speed
- crystals ?
-
- Nick.
