Memory kind of blurs together, but probably was doing larger programs with the tape, 5-9 minutes for a 16kb program [1], felt like forever. Also might be mixed with memories of the C64 cassette which is 30 minutes per 100kb per side [2] so 20 minutes for a 64kb program. I remember it being torture waiting as kid, and I believe it was not always successful and prone to error reading and requiring retries which maybe never worked, seemed like 50/50 chance and eating up lots of time. 1. https://www.sinclairzxworld.com/viewtopic.php?t=39 https://www.sinclairzxworld.com/viewtopic.php?t=39 2. https://en.wikipedia.org/wiki/Commodore_Datasette https://en.wikipedia.org/wiki/Commodore_Datasette
