   Eh, disregard my comment about the pin 12 oddity, that of course relates   
   to the previously discussed 25-pin SERIAL port. Confirmation bias...   
      
   Anyway, there are a few potential problems with the DMA parallel port   
   (not exclusive to Model 90):   
   -the connected device does not understand the protocol   
   -low-level software/driver incompatibility   
   -configuration/user error (setting the link to ECP or EPP...)   
      
   But data transfers between two PS/2s with Type 3 controllers should be   
   relatively trouble-free and pretty fast too!
