I hooked battery cables backwards I changed 100 amp fuse car turns over but won't start 1994 camry I don't know where main fuse is can you help,I hope I didn't ruin computer

The 100 amp is the main fuse, check the smaller AM1 and AM2 fuses, they supply power to the ignition switch, check the rest of the fuses with a test light and the key on, don't forget the fuses on the inside at the left lower dash, the computer is well protected by the fuses and I have never seen one fry due to battery terminal reversal.
