Strange Apple //c problem

Hello, all: I recently got a //c with the 5-1/4" internal drive and was playing around with it last night. It doesn't seem to want to boot DOS 3.3 and it seems to only be able to boot ProDOS disks, which stops after the splash screen (copyright notice) with a "relocation/configuration error". DOS 3.3 won't boot at all. I've seen this error before with ProDOS but I don't remember the reason. This error occurs with both ProDOS 1.1.1 and 1.9 disks, and I tried multiple working disks. This is a strange one but since I don't have much experience with the //c I wanted to throw this problem out to the group. Any thoughts?
