I'm going to try to program a simple keyboard translator using the PIC2455

codes into the pic and I just want to run this by you guys to make sure I'm
on the right track.

Are you talking about a PC keyboard?

<snip>
Is that basicaly all I have to do? Do I need to use pullups or anything
when connecting the lines or even use transistors to source/sink more
current?

Is this a PC keyboard?

(I'm running the keyboard off a 5V supply that can source up to .5mA or so)

1/2 an mA???

Any potential pitfalls with this?

Could be. Is this a PC keyboard and are you really supplying it with
at most half a milliamp??
