Pin 7 on the MC1489 is ground. On my example, I bent the pin over and found a convenient ground point on the board. I then soldered the pin to the ground point Here's a schematic of the circuit I drew for the SB5100 / MC1489 connections. This gives you a serial console output as drew mentioned in another thread.
