Hi -
I used the search function to see if a similar question had come up, so sorry if this is a repeat but I did try

I've had no response from RandyT, so hopefully someone here can offer advice: my KeyWiz 1.0 appears to be broken, although I may just be overlooking something simple. Running a ground and single-switch configuration and testing on a game in MAME shows that some inputs (i.e. Up) work, while most don't (any button, for example, despite reconfiguring the ingame controls).

Any advice? I've had this lying around for a while and have likely shorted/busted it in some way, but there are no obvious cosmetic indicators. IPAC here I come?
Thanks in advance,
Mike
