Consider sticking with period-appropriate storage devices but integrate
emulation-support (rather than interfaces to hard-to-get hardware): DF32,
RL01/RL02, RK05, RX01/02, possibly others ... ? Maybe even TU56 (and TU58).
For example, see:

True. I'm just not too fond of IDE. ;)
We're talking about ATA at different levels. ATA takes (in LBA mode) a
block address, chops it up into very odd groups of bits, and crams those
groups into half a dozen little sections of registers.
And don't get me started on the whole "ATA is better than SCSI because it
doesn't need terminators!" crap that n00bs spill all the time. ;)

Oh, IDE blows dog, there's no question about that amongst people who

get the physical layer talking. There is *nothing* ATA-like about SATA
beyond the name.
Unless you have a microcontroller that has CML-based gigabit transceivers
(and some do, specifically usually for either PCIe or SATA), "lucky" is a
vast understatement. But SATA *is* pretty ATA-like once you get past the
physical layer; it's essentially ATA encapsulated over a different
transport layer.
an
interface. But it all but dominated the low-end computer market for the
better part of two decades.
Once you get beyond that very low-level stuff, ATA isn't too bad.
Amateurish and simplistic, but not too bad.
Are we talking ATA-proper, or ATAPI?
Of course, initializing the transceiver usually takes
more code
than the entire ATA driver did, so there's that.
Yes. ;)
