First, you should test those two chips in working machines to see if they survived the ordeal. Third suspect to cause blackout would be the PLA. You should check that too. Go to Bo Zimmerman's Commodore Archive and read the Plus/4 Service Manual for further steps. Tape is powered form a separate supply circuit. You should check that too with the help of the manual and the schematics. Those can be found there too.
