This is part two of my Retrochallenge 2016/10 journal, where I’m working towards loading ROM images to an Intellivision from an Atari 800. To jump to the very beginning, click here.
OSS DOS XL version 2.42w
After some searching, as far as I could tell, my copy of OSS DOS XL (version 2.42w) has not been archived / preserved yet on the Internet. It’s a variation the disk operating system, called Warp Speed DOS XL, to take advantage of HAPPY 810 & 1050 upgraded Atari floppy drives.
I’ve uploaded the information I have to AtariAge and archive.org.
