The 3740? That's the newcomer in the 8" diskette world. The granddaddy
is the Igar. Hard-sectored, with the sector/index holes near the edge
of the disk instead of near the spindle. Used on IBM 370s, early
3270 controllers, etc. for microcode loading.

And after the Igar, there was still a single density format that was
around for a few years before those newfangled 3740s hit the scene.
