| Happ perfect 360 compatability |
| << < (2/2) |
| MonMotha:
The only compatibility issues I have heard of or noted personally with P360s are that the outputs are push/pull digital or have weak low-side drivers (I don't actually have P360s, so I can't tell you specifically which - I've just done some interfacing for people using them). In most applications this has absolutely no effect, but they don't "wire-or" very well. Specifically, attempting to parallel a P360 with another weak push/pull digital output will result in unreliable operation. Paralleling one with a conventional microswitch based joystick will work, but isn't ideal (as it could destroy the high-side output driver of the P360). You can use low-Vf diodes to get around this if you really have to (even a 1N4148 type will work with most inputs). In most applications, there is no need to wire-or joysticks, so this never comes up. |

I've just bought 2 of these :cheers: ,I got them from this guy http://www.tornadoterrys.com/surplus.htm $75 for two including delivery to the UK. I thought that was a great price, now to start thinking about Kowal's actuators , read about a million posts on these a while ago and was more confused at the end than the beginning , but they did sound great so here we go again :banghead: Thanks for the replies :cheers: |

Apparently, they had tried using P360s with the Tekken adapter, and it was unreliable due to the reasons mentioned. Of course, I wasn't told this until after I had already built the adapter, but I was fortunate enough that the micro I used could out-drive the P360 (though you still get the situation mentioned where there's the possibility of burning out the P360's high-side). Like I said, somewhat of an unusual situation. There are also some potential problems with inputs that are pulled up to voltages other than 5 (12 or 3.3, for example), but I have yet to see such an input on a JAMMA board or even on some of the more custom interfaces I've dealt with like those used in Bemani cabinets. Incidentally, if anybody wants one of said adapter (supports 2 players on JAMMA + extra buttons for SF/MK kick), I think I have 3 left "in stock". |
