Hi Mike,

I have both a 1278B and a sound card interface and a 910H so I'm set up

I'd recommend using the data jacks and keeping the ACC jack for use with 
sound card software.  The problem with using the data jacks is that the 
main and sub band data jacks change when you go from normal mode to 
satellite mode (one might call this a design flaw - others a design feature 

So although you can work the ISS packet system with the TNC wired up to the 
main band jackl, when you go to work a satellite like NO-45 or GO-32 you 
have to take the receive from the sub data port and the transmit from the

modify a PS-2 Keyboard switch box.
