I'm going to try to program a simple keyboard translator using the PIC2455
which has a built in EUSART. At this point I just want to get the

I'm
on the right track.
Are you talking about a PC keyboard?
Yes, Ofcourse... isn't it obvious? ;)
<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???
Ofcourse not!!! .5A ;)
Any potential pitfalls with this?
Could be. Is this a PC keyboard and are you really supplying it with
at most half a milliamp??
