The adaptrers only work well if the encoder board can do both ps/2 & USB.  Almost all current mice can, but keyboards are a totally different story.  The keywiz and hotrod encoders (both ps/2) do NOT do well with adapters.

Ahh, that reminds me.  Mame treats gamepads differently than keybaord or mouse interfaces.  Mame does an extra 8/4-way conversion map with gamepads.  This can be a plus if you know how to use it, but can cause confusion with qbert.

This is not good advice unfortunately. When using a PS/2-only device an adaptor will not work at all. If you mean a converter, this will be useless for gaming since PS/2 to USB keyboard converters cancel all keypresses every 5 seconds or so, to avoid stuck keys, and also have a key-press limit. They are useless for gaming.

USB keyboards have limitations but I must mention at this point that the I-PAC boards, when used in USB mode, have no key-press limitations at all, and are also not limited by the low-speed USB poll rate of 8ms as they use full-speed USB.

hmm i was'nt aware, but that leads me to the obvious question, if usb keyboards have that limitation and ipac presents it self to the computer as a keyboard then how are you getting around this limitation?

Your above statement is pretty "blanket" so im a bit confused.

Put simply, there are conventions which normal keyboard use in the format of the data sent. The conventional format is fine for a keyboard but not acceptable for gaming. The I-PAC departs from the convention.
