I've got a homebrew Z80 based system built from marious magazine articles....
..... And I do have an Atari 800 and 800XL, both bought new back in the day. ;-) You know you're getting old when something you bought new is now "classic" ;-)
Oh yeah, I forgot the 68030 Mac Powerbook I bought at a garage sale for a buck.... the case is broken, but it works.
