I wish I had a hard drive for my Atari back in the day :) Had to survive with extra SF314 drive. Fortunately there was a SM124 monitor to accompany my Philips CM 8833 at least.
1040STFM is still stored inside a waterproof plastic box along with few hundred floppy disks and extra floppy drive. Seemed to be working a few years ago.
Blammo. Within about a second I was looking at the desktop.
This was so much fun to see that I hit reset about 30 times in the next minute or so. Reset. Desktop. Reset. Desktop. Wheeee!
Most BIOS-based computers won't get to a single desktop in that amount of time. I don't know what they're doing, but most of it is not useful to me.
