Exactly the same for me, I reckon a lot of 80s kids in the UK who had the right amount of attention span to do it were the same. I remember trying to input the massive list of hex for Tim Follin's 3 channel sound routine that I somehow managed to mistype a part of AND mistype the checksum so that it validated! Cue instant crash every time and disassembling was beyond me at that point. In the 90s I got an Amiga and discovered the demoscene (basically showing off as mentioned in another comment). Fast forward another decade and bored at my parents after finishing Uni I dragged my Speccy out of storage and managed to get the Tim Follin music routine running! And found an assembler and did some Z80 assembler demo effects for the lulz. As you said: good times.
