TalkingOctopus:
Hey, thanks for your input. I've already got a lot of images from your website.
Your machine is cool looking, and I probably should have just referenced it. I figure it coudln't hurt to ask though

I'm going to go with a cardboard proto if I can bring myself to order $300 worth of stuff from 'bobroberts' or happs.
Heh, my 7 button layout is supposed to look like the NeoGeo controls (Mslug!), but the templates from here don't look like that. I guess I just got lazy.
I'm going to agree with your judgement of the 3 "Missle Command" buttons.
I'll just go ahead and use some other buttons.
I appreciate the input.
