We use a product from Excellink on all the series 3's and 4's
connected to our 3000.  One of the advantages of these connections
is that they have multiple serial ports _AND_ a parallel port, so
you can connect your printer to the 3K and to a PC!

Prices are pretty reasonable, too.  the part number you want is:
 
      JC/MIO3000-2 at $349. a piece (in October, 1994).
 
Hope this helps!
 
 
I know the thoughts expressed here are my own because no one else would claim
