I am trying to determine if you mean the keyboard isn't working
other than the resets, or isn't typing the correct characters.
If the prior, check that the cable is tight in both the MB and
the KB, but the latter is easier, just flip the keyboard switch
on the top of the case from DVORAK to QWERTY. Other than those
2 things, your best bet would be to have me send you another KB
to try in it. I have several good working ones. Will trade one
good one for your defunct model. BTW, what does yours return if
you type "PRINT PEEK(64447)" from the BASIC prompt???
