IPAC 2 query *solved*

Yes the little adaptor will work on all I-PACs.

You need something that does NOT convert the protocol from PS/2 to USB. The I-PAC is already USB and auto-detects the type of interface its connected to, switching to the correct protocol as required.

If you use a converter, the I-PAC will run in PS/2 mode, not USB, and the converter will attepmt to transalate to USB. This will not work for gaming. The main problem is these converters cancel all keypresses after 2-3 seconds to avoid stuck keys. Thats useless for gaming of course.

Just an update on the new problems. Last night, even the coin slot stopped working. I opened up the coin door, and all the new probs went away. Quite obviously, i had shorted something. So now I'm back to just that problem of the two button interference. I have four days off now, so hopefully i can get around to lugging the pc over to the cab (",)

Just an update on my ipac oddyssey (",)

I picked up one of those little adapters a few weeks ago from the local ipac dealer. I took one look at it and thought that he'd sent me the wrong part. For some reason it looked like it converted a USB cable to ps2. Today I looked at it again and it quite obviously does what I was told it would do. It changes the end of a ps2 cable to a usb. Which is exactly what I needed. This is the part Andy is talking about



So I set it up, changing the jumper on the ipac to usb. restart the cab, let it update the drivers for it and tried it out. It works, which is good, but still exactly the same problem as before  :(

While I was in a testin' mood, I finally dragged my duel boot pc over to the cab to try the ipac on that. Booted up, and then the monitor shut down! I rebooted it into Linux, and everything was fine. Hmmm. Tried windows again. Again with the black screen. Booted into Linux and desperately had a look to see if I had mame on it. Nope. Set the pc back where I grabbed it from, and it boots into windows just fine! WTF? I sure am surrounded by a lot of crappy equipment!

So anyway, this is what I've eliminated for sure so far:

mame cabs ps2 connection (same problem occurred in USB mode)
the ps2 cable in the cab (I used a spare to hook up the pc to the ipac)

Basically, in all this time, I still haven't figured out whether it's the IPAC or the mame cab pc!


I will try and get a friend over with mame on a laptop and try again. To be continued...

Edit: Just re-read my first post. Maybe I have narrowed it down to the ipac. The ipac has the same problem with either ps2 or usb. But when I tried a usb gamepad, no problem. Bugger. Oh wait. I also tried it with a ps2 keyboard and it had the problem. What the hell. I might go and try the game pad and the keyboard again to verify.

I'm confused.. Isn't that exactly what he told you NOT to use?

No, all the little adapter I used does is physically (not electronically) convert the end of a ps2 cable to USB. The ipac is USB already. Move the jumper to USB and now the whole thing is USB.
