Before Amiga I was an Atari 800 guy... I can remember being exstatic about finally getting that 88k floppy drive! and the 16k upgrade... with the 800XL, the big deal was doing the 265k RAM upgrade and getting HD like performance from the ramdisk. I did some programming in Atari Basic, and Action!, a language that existed nowhere else. I used it to write this WYSIWYG lable printing thing which was so huge, it couldn't run on the machine with the Action! cartridge plugged in. (Compiler in a cart, wow!) So I dragged out my old non-XL 800 and hooked it up to the Atairi's serial peripheral bus in a crude networking setup. Compile the program to a real floppy, than boot the other computer from it to test the latest changes...
fun times. ;-)
