I never had any purpose-made recordable 8-track tapes. Instead I was recording over someone else’s country/western music tapes. For the good of humanity. Each program took only 14 minutes (typically, to store all of memory from 0800-BFFF, the end of RAM on the Apple II series) of space. I could put one program on each track.
Sadly, my country/western eradication program did not extend to cassette tapes. I was stuck in a Volvo station wagon for two days, driving from Toronto to Winnipeg in the middle of winter, with three smokers and their country-western Christmas carol collection. Some times I still wake up screaming.
