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.
