Dave Dunfield has a test program which determines if your FDC can

Download the TestFDC program.
Any sense of what PC models / controllers are
capable of this task?
Anything that will run ImageDisk or Teledisk will work. It doesn?t
necessarily have to be one of those computers, you could pull the 360k
drives from one of them and hook them into a ?newer? PC that still has
5.25? 360k floppy support. There?s usually 360k floppy support on
motherboards up to the Pentium III era. I personally use an old ABIT KT7A-RAID board which has
a controller
which is capable of writing single-density/FM disks. I?ve got a
half-height 5.25? 360k drive in it connected as drive B and a 3.5? 1.44M
as drive A. I?ve used it quite often to create disks from my original
TRS-80 Model I which can only do SSSD. I?ve also used it to make disks
for the Kaypro and even make disks for my HP-150 which uses single-sided
3.5? disks.
Be advised that not all KT7A boards are created equal. I had one for a
while, until I discovered it would NOT write single-density disk images,
even though it's listed as supporting SD in Dave Dunfield's registry (same
page). I replaced it with an Abit KV8PRO, which takes an Athlon CPU, with
onboard 10/100/1000 ethernet, 1 AGP 8X/4X slot, 5 PCI slots, SATA and IDE
drive support, and 4 USB ports. No problem with single-density, on either
5-1/4" or 8" drives.
