I just spent a couple hours the other day resurrecting an 800 from the dead. Good stuff.
That's a 400, not an 800 you barbarian!
Actually, I have a 600XL (256 kB modded) two 400's (one with 48 kB Ram) and one 800 laying around somewhere. (Not an 800XL, but the real thing

) Just saw on the internet someone managed to build a modern ide harddisk inside an 800XL? That's challenging
