I just finished hooking up my A1000, Which my dad bought in 85. It hasent been powered on since I got my A500, but I just got rid of it, so I hooked it back up.. and she booted in to WB 1.3 just fine! I made my first modification to this A1000 when I was 9, I changed the LED's in the compy to yellow instead of red. (I dont know why, I was 9!) They work fine as well still.
