I know. There's even instructions for how to build one online (http://searle.hostei.com/grant/JupiterAce/JupiterAce.html http://searle.hostei.com/grant/JupiterAce/JupiterAce.html, the very site that I used as a basis for my design, no less) But that has (gasp!) a screen, and while I could no doubt program it (with some trial and error, because I suck), I very much doubt I could actually build it. Maybe if this design works (dubious, but perhaps eventually), I'll give it a shot.
