cards just use the standard ATA interface, there are a half-dozen or so
cards that implement that on the Apple II already.
Unfortunately not. Only CF *memory* cards support a "true IDE mode" that
is ATA-compatible. All other cards use the PC-card IO- and/or
Memory-Mode, which is close to the PCMCIA (PC-card) standard.
In "true IDE mode" you have three adress lines and two chip selects to
address the ATA task file. Easily mapped into the /DEVSEL area. The
PC-card modes use 11 address and 16 data lines.
