I still have one of my old BASIC tapes from way back in the day; I 
wanted to get the code back, or just remember why I had saved the tape?

One of my linux user group buddies locally rigged up an optical reader 
(IF) to a single board micro controller... we pulled the tape by hand 
using the center drive holes (sprocket holes) as a strobe and after a 
couple of false attempts read the entire tape into a text file.

That tape still have the caster oil smell of the tty that produced it; 
smell has a very strong memory association /  I can still hear that 
thing running in my head.  ... haven't seen one physically in years.
