I once paid £500 for 4MB of RAM for my Amiga500 in about 1993 with dreams of using it with the finest animation software, so I could become a computer animation god. Nothing supported it and it made most programs which did support it randomly crash. The money was all my birthday and Christmas money combined. I still wince when I think about it today. I still have the RAM module. I just can't let it go. What computer/gaming disasters are you guilty of?
