It's IDE on a smaller pin pitch I think. Certainly
there's no smarts to the
IDE-CF convertor that I have here - CF socket, power socket, IDE socket, a
capacitor, and a jumper for master/slave. That's it.
And like SCSI, interfacing to IDE is mainly a software
issue - the hardware
tends to be a few buffers and little more.
As if using CF in memory Mode not even that. Still, you need
(beside MS-DOS file system et al) to have enough free interface
lines and beeing able to folow a protocoll with multiple control
lines. If you realy look for a simple and easy modern readable
media to interface for most computers, I would recommend MMC (and
compatible SD-Card) media. As most basic interface they support
SPI, a 4 wire serial bus that can operate at any speed from zero
to 20 MHz with almost no need for additional hardware.
A year ago I did even an implementation using the Apple ][ game
port. No need to say that the transferrate was rather slow, still
on par with floppy speed :)
