Yep, did that back in the day. Imagine the fun of soldering diodes back in to correct a mistake or change the program. True, it was usually just a bootstrap, but it was sure a lot better than having to toggle it in every time. The first mini I programmed (Varian 620i in 1968) had only 4096 16-bit words (8K bytes). I am sure that many others on this list have similar stories. Back then we did the impossible with nothing.
