And I just realized I have a program for formatting the CFFA that is only about 400 bytes long. But since you can't even boot into prodos cause your CFFA is the only device, typing in this short formatting program would do you no good as well and also it only works under v2.0.I'm not following exactly what is going on/going wrong here, but is it ProDOS formatting of the CF card that is missing? You could bootstrap ProDOS and ADTPro over an audio or serial link, and then use the format function from ADTPro...
That's an option I hadn't considered! Unfortunately, I have neither a USB-serial port adapter nor a suitable cable at the moment. Since this project began as a quick test of whether the SD-CF adapter would be a slam dunk, I think I can safely report that it isn't! ;-) I'll defer trickier solutions until I'm back with my main setup, which has lots of I/O devices, knocking the level of difficulty down from an 8 to a 2. ;-) At this point, my main hypotheses are 1) a timing problem with the SD-CF adapter and the CFFA, or 2) a block-numbering problem. Looking at blocks in a block editor would quickly rule out 2), so that will probably be my next step. Then I'll try using a v2.0 CFFA, since that may have different timing requirements on its CF port. -michael NadaNet 3.1 for Apple II parallel computing!
