Q: Can I use a real floppy drive with the Replay board?
A: Maybe in the future, user JimDrew is working on something called the SuperCard Pro
Last year I designed SuperCard Pro, which was suppose to be a simple flux level disk copier that lets you use PC floppy drives to duplicate Commodore 64 and Amiga disks. That turned into a 25ns resolution disk copier that can duplicate virtually every format and also create images of disks (flux level, so copy protection included). In the last 45 days I caved in to temptation and redesigned the hardware to allow it to not only be a disk copier, but also be a floppy drive emulator. It has a micro-SD media card to load disk images. It has two high speed serial ports that can be used to control it, transfer raw data, get directories, etc.
I am waiting to get the FPGA board from Mike, and I can look at exactly what needs to happen on the FPGA side to fetch data. I think the best way to handle this would be interface the data stream into the PAULA's data separator (providing PAULA is emulated at a low level). If there is PAULA emulation, then there should be no problems running any type of copy protection you can throw at it. If the PAULA emulation is limited, it still might be possible to inject the properly timed MFM data into the system.
I wrote many disk copiers and designed several disk copying hardware devices for the Amiga, so I am extremely familiar with what is necessary to accomplish this. So, hopefully I can work with Mike to provide not only emulated disk support, but also real floppy drive support since SuperCard Pro can do both.
