Does anybody have a scanned version
of the TRS Pocket PC or the Sharp PC-1211
aviable.

I've recently obtained one (TRS-type) including
printer/cassette interface but after installing new
batteries the machine seem a rather psychotic and is
only eratically reacting toa few keypresses. I locks up
pretty soon after. A reset does give a reaction that
seems normal. PCB's and keyboard look ok,
so the CPU is still doing something ?????

On the backside of the main PCB there are two
capacitors (small tanlatium) that seem to have
been blown (could be RF-filters also) I can't really
see the because of a ribboncable. Anyway
these components have spilled some debris on the PCB
so something is wrong there .....
