I have a run 5 CFFA that I want to put in my shiny new B&H Apple ][. It's a non-plus model with raised power key and everything. There are integer ROMs on the motherboard, and I have a ROM expander with Applesoft that I can switch in. When I plug in my CFFA, jumper it for 6502 and boot up ProDOS 1.9, it complains of a relocation error and locks up.
I have a feeling this has more to do with ProDOS running on the hardware rather than a CFFA-specific issue. But does it sound like it should even be possible to run ProDOS on this setup, much less boot the CFFA?
