I have been playing with the PC's AppleWin emulator source code. I added HD support and have been making the built-in emulated cards (Disk II, SSC, MockingBoards) slot independent (and duplicatable, so you can have multiple of each). I have also created a spec to add additional cards via DLLs that the emulator looks for at run time.
What I need now is programming documentation for some of the standard Apple II peripheral cards. I don't really need user documentation. Mostly just docs on their IO ports (and ROM images for any of the cards I choose to emulate that I don't already own).
Does anyone know of a centralized location with a decent collection of these specifications?
