The day I accidentally discovered my A2000 contained a bootable harddisk...
My father found and purchased an A2000 for me from an auction late 1997. I've only ever used an A1000 and A500, both had 1MB of ram and Kick 1.2. It looked like it was identical, only the "insert workbench" screen was colourful as it ran KS2.04
One day (new years eve), I accidentally reboot my A2000 twice with CTRL+A+A, and just as I was going to insert my workbench disk, it starts booting up on it's own! I found out much later that it contained a FLASH2000 hard-card with WB2 preinstalled, 80MB quantum fireball harddisk, and 8MB of RAM - the HDD didn't spin up in time for the first reboot, and required a second.
I was completely entranced by my new 16 colour workbench, and spent most of the day playing with WB background patterns, completely ignoring everything else. I really didn't want to go out for new years eve that night, I just wanted to stay home and play with my new toy!
The sad thing is, these days, I could never get that excited about anything.
