I believe most machines that use a Western Digital Floppy Disk Controller (1771 or 1793) rely on this. Some PC controllers also rely on it and have trouble reading TRS-80 disks generated by some operating systems because there is insufficient gap after the index hole before the sector starts.
Wanted: S-100 Bus components - please PM me if you have any. They don't even need to work!
