-
- Current versions of the A3010 don't actually have the ARM250 chip in them.
- They actually have an adapter board with the same footprint and pinouts as
- the ARM250 which has the ARM2, VIDC, MEMC1a and IOC chips on it.
-
- I would have thought that an ARM3 upgrade for this version of the machine is
- quite feasible, being no more difficult than the upgrade for current A3000
- owners.
-
- The likelihood of such an upgrade being made available is small, as most of
- the machines will contain the ARM250 in the near future.
-
- If you have access to a surface mount soldering station, and can sort out
- the clock rates for the ARM3 then I see no reason why you shouldn't fit
- an ARM3 from any of the current suppliers of the upgrade.
-
- You should, of course, not attempt this while your machine is in
- warranty.......... :-)
