I actually have an IDE "controller" somewhere which is just a tiny PCB with
an ISA connector on one side and a 40 pin IDE connector on the other, along
with a couple of ICs (presumably buffers/latches, but I don't know without
finding it). It's somewhat unusual, given that IDE ports were normally
included as part of multi-I/O boards, or (a little later) often
incorporated into the motherboard.
