Most problematic was the Keyboard and HDD.
So "overcloking" must be done very carefully and people must know exactly what they are doing.
Not only Hardware failures are to expect but also data corruption are likely to happen.

Yep and this is why Monte is constantly toggling the 41CL speed (>x1 to x1 and back) to address those kind of issues (mostly IO's).

There is a RAM and speed upgrade available (here and here) for the HP-42S.

Best, Sylvain
