Oh snap, I totally remember what that joystick was called I used back in the day. It was the Hotrod SE
https://www.ebay.com/itm/194463418003?hash=item2d46ec4693:g:NtsAAOSwqEJhdcN4 It uses Happ style joysticks and if you don't mind tearing it apart, the Tornado Terry sticks swap right in. Of course, back then, the Hotrod SE ran on I believe serial port or PS2. Loved that stick. I'm a right handed (pac-genre) player as is my son, so I had my Hotrod configured with a Tornado Terry on the right joystick, and the standard happ 8 way on the left. I sold mine off after I bought the new house and had room to make an arcade room with controls the way I like on my cabs. But still, loved that Hotrod SE. I linked to one I found on eBay as you can see (though not the SE version). Like I said though, NOT USB, but honestly, would really not take much to pull out the encoder and swap in an iPac, and do like I said I did on my old one, swap out one of the sticks for a Tornado Terry. Then you get both a dedicated Pacman genre stick, and an 8 way for that genre. I mean, otherwise, building your own control panel really isn't as hard as you might think and honestly is not expensive if you don't mind fabbing your own. Myself I suck at woodwork, can barely assemble IKEA crap, so I had my local cabinet company do the cuts for me and pre drill holes. The rest is simple (to me anyways) electrical hookup and screwing down a couple buttons and joystick.
time to hack a KEYBOARD to play just your PACMAN.
Get a 4-way stick, hack and old keyboard and wire it up.
HEEHEE, reminds me of the good ole' days before Andy came out with the iPac. Great way to brush up on soldering practice.
