OSI C3A Diskette Images

The Ohio Scientifice C3 was state of the art in the late 1970s and came equipped with three of the most popular CPUs; 6502, Z80, 6800. But it's really cool feature was the dual 8" floppies that could hold 300KB of data.

Below are some of the diskettes I have captured from my old floppies using the C3dump program. Initally these were captures on a serial terminal as ASCII dumps. They have been converted to binary images using my own OSI Disk Dump (osidd) utility.
