That would be one way to do it - I have a 2031LP that I tend to use
most often with my 3032 (US 2001-32N) PET, mostly because it weighs
less than my 4040.

Were those really so common?  In my area, perhaps because of when the
PET was popular, I saw more 4040 drives.  All of mine are upgraded
2040s (new DOS ROMs and 6530s).

Ultimately, though, it should be possible to adapt an IDE disk to any
IEEE drive, as long as someone with the necessary skills and equipment
(and time ;-) has a particular variety.

That sounds like a larger version of my pile.  I have plenty of CPUs
prior to the B-series (PETs of most flavors of ROM and video types,
VIC/VC-20s, C64s...), most of the disk drives (no tall 2031, no 8",
nothing newer than the 8250, but including working D9060 and D9090
drives).  I really should go over my pile and see about thinning the
herd where it comes to duplicates.
