Same problem here with a PC-1403

Thanks for the tip.

Funny thing is machine is unresponsive to ON/OFF switch position. Remains BUSY even if tab in OFF position. Reset buttom does not help. Switches off when Reset pressed, but return to BUSY when Reset released. No obvious corrosion/dirt on board.

Anyway, a nice looking machine. I do not think I would make much use of it, even if it worked.

Sounds like about the same issue as mine. I can turn if off if I switch it off and then press the Reset button, but attempting to hit Reset while it's in the on position has the behavior your describe.

I'll have to give it another look with the magnifier and see if I can find any iffy looking solder joints.
