Intro and floppy test program

[dgesswein]

The first computer I used was an OSI. The high school had a cassette based probably 1P or 2P and a Challenger II with dual 8" floppy drives and video board. I spent a lot of time on those machines starting with playing games, then writing some, then making modifications to the operating system to make it less annoying. A while ago a friend gave me a Challenger II similar to what I used. Its running and I showed it off at VCF 2016. The floppy drives were acting up so I wrote a floppy drive test program. Hopping to assemble and play with replica 560Z and 430 I got to show some more things at the next VCF east in October.
