--- Quote from: microwrx on August 11, 2004, 06:44:39 pm ---Can someone confirm whether or not the different options and prices are really just for different harnesses? I really can't believe Andy would go to the trouble of having different chip configurations for different options on the same product. It makes more sense for it to support everything and you just purchase the option with the correct harness (or one without any harness and make your own). --- End quote --- I can't confirm this, but . . . I know the Opti-Pac has a jumper for Active Hi / Active Lo . . . I don't think the mini-pac does . . . I know Andy says that one version of the MiniPac works with the Happs Trackball and one works with the Ultimarc tracball. And neither one will work with Wico/Suzo. I know (from other BYOAC'er s ) that the Ultimarc tracball has one active hi and one active lo board. Happ trackballs are either both Active Hi or both Active Lo. I suspect the different MiniPac boards account for the difference in Active Hi or Active Lo circuitry. I also know that you can order the Wico Trackball as either Active Hi or Active Lo. I would suspect that if you ordered the Wico Trackball in the same configuration as the Happ Trackball (Lo or Hi) it should work with the MiniPac, but I can't confirm. Would be nice if Andy could shed some more light on the subject. . . |

At the present time, for the current batch of MkI Mini-PACs, all boards are the same. This will change when we go to the MK II board which will support the WinIPAC IPD software and will be jumper-less. The differences are only in the harness, the Happ has different connectors to the Ultimarc trackball. The Ultimarc trackball does not have one active hi and one active lo axis, this would be silly! The difference between the special Ultimarc trackball and the ordinary (and Wico) trackball is that it has 2.2K pull-up resistors added onto all 4 outputs. The Happ trackball does not need these because it has driver chips on the opto boards. The current Mini-PAC boards don't have any pull-ups on the trackball inputs but the new boards will have, thus eliminating the need for the special trackballs. Andy. |

The Wico t-balls can be ordered as either Active Hi or Active Lo - see http://www.wicothesource.com/new2/pages/page89.htm Can a Wico t-ball in the proper configuration (Lo or Hi) be used with the MK1 minipac. --- Quote ---The current Mini-PAC boards don't have any pull-ups on the trackball inputs but the new boards will have, thus eliminating the need for the special trackballs. --- End quote --- Will the new boards then have a jumper for active hi or active lo, or will they auto-sense this somehow, or am I missing the point altogether again? Thanks for clarifying, BTW. |
