I bought the ConnectPro Master-IT USB switch to share keyboard, mouse & monitor between my PC and Powermac. It didn't work very well at first and I did a search. I found some post on some forum where the guy gave very specific instructions on how you had to hook it up in some special sequence to get it to work properly. I did that and ... voila ... it worked GREAT! Well, then the hard drive crapped out on my Powermac and I had to disconnect it all. Now, I CAN'T FIND the forum post that told me how to hook it all up correctly. Now the numlock pad on the apple keyboard doesn't work and I've got the blues.
