Source code for PET-era CBM hard disks. Uploaded by Dennis Jarvis.
The archive contains also two PET programs. DOSSUPPORT is an
early version of the DOS WEDGE. You load and run it like a BASIC program.
Editor is some kind of editor program that loads at hex 7000 and is run by
SYS 7*4096. It adds the following commands: auto, break, change, delete,
find, format, get, kill, load, number, put, repeat, and save. I have not
figured out the complete syntax of most of the commands. Both of these
programs are compatible with BASIC 2 only. This information was supplied
by William Levak.
