Question: do CF cards support 8 bit transfers though,
and are they
guaranteed to do so? IDE interfaces have been homebrewed to a lot of
vintage machines, but quite often they only support drives that'll do 8
bit data transfers.
Yep, they do.
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.
Yes, you are sure
And like SCSI, interfacing to IDE is mainly a software
issue - the
hardware tends to be a few buffers and little more.
This is "not so easy" as you may think. But my three-layers-approach
seems to fit nicely here.
Anyone has the protocol of a QIC-80 drive? I'd like to take a peek on
that.
BTW, remember: This does not need to be a CF card, it can even be some
cheap SRAM memory and a serial or ethernet connection... :o)
