        I think perhaps some manufacturers' chips must be more robust than
others, because I _have_ seen TTL's get zapped by supply voltages exceeding
5.25Vdc before, even when the supply didn't drift as far as 6Vdc...
Nonetheless, it can't hurt to adjust the voltage down to read a proper 5V
at the edge connector and see if things start working -- you might get
lucky. :) And if the board still doesn't work, you're no worse off than
you were before...
