If you want to run Apple II Workstation Cards on a network, and also want
to have some workstations' printers directly connected to the serial port
on the Workstation card, try the following solution:
Install the card in slot 7 on the Apple II.
Run the new Chooser II (ver. 1.2.1) software. When the Apple II WorkStation
Card is installed, a new option window appears in the lower righthand corner
that allows the output to be directed to either the serial port or the
AppleTalk port on the card. Once the serial port is selected, everything
should work perfectly.
