Semi-OT: Has any interfaced a 360K floppy to a pentium-class PC?

Maybe for copying disks? But there's no reason to waste anything better
than a 286 on that...

My nice ASUS dual-athlon board has options for other things, and also
works with a 360k drive. I've never seen anything myself that's a PC and
doesn't support 360k drives...

Probably not... it's really hard to find a new computer with ISA slots

Not that I've seen. Any PC with PCI slots generally has a chipset that
has an onboard floppy controller.

Well, maybe. If the hardware (chipset) doesn't support the lower data
rate, you're probably out of luck. However, there are programs that will
read and write to disk (like TeleDisk for example) using I/O to the
controller. Anyways, if you can't disable the floppy controller in the
BIOS, you're not likely to get a replacement to work, anyways. The
onboard one will either 'compete' with the ISA card for I/O and
interrupts, or the ISA card won't even see the I/O to the port.

VERY understandable. Good performance for the price. Bad quality (for
stuff that has the good price) and karma.
