This is the source code to an unfinished extension that introduced lots of commands into STOS Basic to deal with the Atari STE. It contains commands to interact with the Jaguar controllers, along with automated hardware scrolling commands, and reading joysticks that are connected to the Centronics ports.

This is the full source code to Disk Boot v1.00 that I created for my A-Level project from 1992/1993.
Disk Boot is a floppy disk boot sector management application that allows the copying, storing and restoring of boot sectors on a floppy disk. The main idea for the program was to enable the recreation of boot sectors where they had been overwritten accidentally, or by a boot sector virus.
Along with the program is the extension that I created to allow STOS Basic to do some low level disk functions, and a series of pre-saved boot sectors.
I have also included all my thesis notes about the project in the PDF file.
** NOTE: I cannot guarantee the operation of this program, and therefore cannot be held responsible for any damage or loss of data as a result of using it!
