This would be too slow to be practical. If you could get a gamma count every second then it's better.
1024 Bytes / KB

1024^2 Bytes/MB *1.44 MB/floppy = 1509949.44 Bytes /Floppy Disk

At a rate of one random bit per second is 8 seconds per byte

= 12079595.52 s = ~139.8 days. Too slow.

Need to figure out a way to sample faster. I've never done this personally but I'd like to try it as an experiment. If you get something like this going, make a youtube video with instructions.
