: Z; : First of all; welcome to the insanity!! : To be honest, the 4-1/2" trackball is probably a little bit over-the-top. I originally had designs on this ball too, but was swayed by comments of it's heaviness as well as finding out that most arcade trackballs are the 3" type (Marble Madness, Golden Tee, Centipede etc.) : I don't know too much about the Happ USB interface, but if you plan to put your finished controller into a cabinet at some stage down the road, the programmability of an OptiPAC or a Hagstrom encoder may be a better and cheaper choice. Keep in mind that getting USB to work in pure DOS is problematic to say the least... : One of the best things about this site is the Examples page where there are several write-ups of stand-alone controllers to be found. In addition the folks on this message board are about the most helpful and patient people around so feel free to ask any questions you may have - I'm sure you'll get PLENTY of input... : Good Luck and welcome! : Mark : : As a beginner in this area I'm looking for any help : : or advice you may be able to give me. : : I've wanted to start an Arcade project for some time now. Unfortunately I live in Bermuda and the market : : for old Arcade Cabs to modify is nill. Building : : from scratch is my only alternative. Before I embark : : on this project, I thought about getting my feet wet : : on a smaller controller project. I already own a HotRod so I was thinking of a Trackball or Spinner project. : : I was thinking of one trackball and three buttons in the design. Over at Happ, I was looking at the following: : : For the Interface, Happ offer this nice USB jobby. It : : looks like it will meet my needs. : : http://www.happcontrols.com/amusement/trackballs/55022600.htm : : My question is - Will I be able to use the 4 1/2" ball : : (part no. 55-0300-00) or does it only support the : : 2 1/4" trackball (part no. 56-5500-10) : : Another question is on the buttons. I'd like buttons : : like those in the HotRod. These look to be same same. : : http://www.happcontrols.com/amusement/pushbutts/5891xxl.htm : : I know these are questions I should be asking Happ. : : But I am hoping someone else has looked at these before : : and can save me from making an expensive mistake! : : I would appreciate any advice you can give. : : Thanks in advance. : : Z
