The DigiBoard DigiChannel PC-8/Xe I/O Controller was about
$350 and the octicable was about another $50 last time I
looked. This provides 8 lines of serial I/O. I think you can
find much cheaper boards than this. Your best bet is to get
'Computer Shopper' and take a look. I have used the DigiBoard,
however, and it is a very robust board. In the latest shopper,
Computer Discount Warehouse (800) 726-4CDW has the PC/8 for
$424.73 and the PC/4 for $286.10.
