Analog controls in pure DOS, no gameport!

Oh, I should have mentioned that I'm not doing anything irreversable to the Vectrex. It'll even still play Vectrex games through MESS. That's part of why I'm having a hard time... I don't want to destroy the original guts to make this work. :)

The mobo has a PCI slot, but there's definitely no room to add an expansion card. It's a really, really tight fit.

Wow! Those joymice are really expensive! Thanks for pointing them out, though.

The original Vectrex controllers are analog. It's going to require some unique thinking to achieve my goal of making them work without modifying one because of the way they work. They take -5v and +5v input and vary the output between -3.25v and +3.25v. -3.25v is far left, 0v is center and +3.25v is far right. However, I'm not worried too much about coming up with a circuit to translate that into +0 through 5v.

Those mini-itx boards support the use of certain riser cards that will make a PCI card lie parallel to the motherboard rather than perpendicular to it.  I'd try one of those and a soundcard with a gameport.

I think even that won't fit, but even so, do PCI soundcards exsist with gameports?

Until recently, most of them had game ports.  My Audigy Platinum had a game port that had its own slot bracket and plugged into the sound card.

Of course, if you're planning on doing DOS, you need a seriously DOS compatible sound card.  I'd look at the Sound Blaster 16 boards coveted by the DOS MAME guys.  Note that there's like a bunch of different cards marketed under the SB16 name so you have to go by the CT model numbers to be sure what you're getting.

SB Live has a gameport.
