I had the Atari 400 as my first computer, tape drive that took 45 minutes to load a game, upgraded to the SS/SD 5.25 floppy which made things a whole lot easier. I hacked together an external keyboard from an old teletype machine and a LOT wiring, and ribbon cables to get a "real" keyboard for it. I spent so much money on that thing doing upgrades, wish I had that money right now. :)
