Wozboot 13

This disk image (Woz and a2r format) contains a “DOS 3.2 System Master” dated 3/21/1990. The most interesting thing on here is an Integer Basic program called “WOZBOOT 13” that claims to have been written by Woz himself. The program takes a 13-sector disk and makes it bootable on 13- (5:3) or 16-sector (6:2) machines by relocating data away from a 5:3 sector in track 0 and replacing the sector with a 6:2 sector 0 with boot code to load the original 5:3 sector 0.

The Woz image boots in Virtual II.

The other curiosity is… who would create a pretend/updated DOS 3.2 master disk in 1990? Well, based on the writing on the disk and other hints, that'd be 13-year-old me. I guess I didn't have much going on that year.
