I wish this had been announced 1 week earlier when I started my most recent project. 

I just hacked an old MadCatz Play Station steering wheel which had 10k pots.  (Side note:  it seems a lot of PS2 devices use 10k pots in the analog controls)
I replaced the 10k pots with 5k pots and wired it to Dave's AKI interface.  If I had the A-PAC board is it correct that I could have just used the 10k pots?

you'd just have to use the corrisponding capacitor.

first, i'd like to say that adding a device numbering scheme would be nice.  the mroe complicated our machines get, the more interface devices were gonna have, and the larger possibility for needing two of these on one comp.

also, i like the eight axis idea.  that way us driving cab guys could always have our pedals hooked up and still have enough inputs for our yokes and analog sticks.

and lastly, how does mame like analog sticks?  do games actually accept this kind of input?  thanks for the help guys.  and keep up the good work andy.

I ordered mine (along with a trackball and a t-stick plus)!!

It is so cool that something new came out right when I was working on a new project.
JODY:
My only question is concerning the "no calibration will ever normally be needed".  Is the analog to digital conversion going to be able to handle pots OK that have their movement limited by the way they are used in controls?  And pots that have different ranges?

It would seem so by the description, but how does it know what the range is?  Does it still need to be calibrated in Windows?  Is there something in Mame to set?  Hopefully it isn't per game...

Andy, are you planning on releasing a PS2 adapter anytime soon?
