Also, the way companies "copy protected" their floppies would be to permanently damage a sector, then search for that sector in the code. Until software was created to replicate the sector bad calls when running such code.

Also, I loved how I could peek and poke graphical elements into my code, so that when I did a listing, the peeked value for 15360 on the TRS80 (first memory location for the top most left pixel) could be stored in the first byte of some string array by poking into that array's memory location. Then we would write an app where we drew the game screen, then peeked the video memory, and poked it into a series of string arrays, then go to that game program and finish coding it. Oh the days... and the stupid stuff I still remember after 30 years, yikes.
I used to use poke a lot in my code, I remember 15360 fondly. In H.S. as a nerd I called myself "Practical Poker" -Yeah, just doesn't sound right now.
