This belongs in a new thread, but. . .
Anyone have an opinion on KeyWhiz versus iPac?
Yep, most everyone does - Been debated a lot, - search old threads -
Key points -
KeyWiz is less expensive in US.
KeyWiz 36 inputs, I-PAC 32
I-PAC has PS/2 or USB support. KeyWiz is only PS/2
I-PAC has keyboard LED support.
KeyWiz has more flexible shift function.
I found KeyWiz software more intuitive.
Keywiz has switch-selectable keyboard pass-thru. I-PAC has automatic pass-thru.
KeyWiz uses SDRAM, I-PAC uses EEPROM.
KeyWiz has a screw terminal for +5V output, I-PAC has a pin header for this.
I-PAC's can be daisy-chained if necessary.
There is also the I-PAC VE which has 32 inputs, but uses SDRAM and is USB only, but is less expensive than the I-PAC/2.
Just getting started so I haven't ordered either yet. Also, what's the benefit of OptiPac or iPac mini over iPac?
I-PAC and KeyWiz are functionally equivalent to a keyboard hack. Opti-pac is functionally equivalent to a mouse hack - i.e. trackballs, spinners, steering wheels, optical rotary joysticks, etc. Mini-PAC is similar to an I-PAC with a pin header instead of screw terminals, and the optical version of it is similar to an I-PAC with half an opti-pac added.
One more button question. Is it possible to assign more than one key to a single button? I read someone somewhere had a button on their cab to push whenever MAME asked you to type 'OK'.
Not really, I read the I-PAC software was going to support this, but I don't think it does yet. If you didn't mind losing an input, you could wire the button to two inputs, but I think MAME is looking for O followed by K, not both inputs simultaneously.
Anyone else do this? If not, do you type 'OK' every time you load up a game?
Heck no!, Run NoNameMAME and disable all that stuff.
