- This is not quite correct:
- I started using 22DISK with a hardware patched XT controller card, which
- was able to do the _single_ density on track 0. I left it for a Seagate
- ST02 SCSI/FD controller, which, to my amazement, was able to do it as well!
- So maybe there are other controllers who do it as well.
