Both - more so with the early Dave-made stuff. The later examples, done
with a much better writer have had less problems but still are nowhere
near perfect. And some of the "factory" optical media have developed
garbles and drop-outs.

My only Commode Door calculator is the little "stocking stuffer"/novelty
that looked like a 3.5" disk and was solar powered. I sold as many of
those as I could get my hands on (less the one I still have) when I had
my confuser store.
