HUGE differences, Chuck - 3 slots, no onboard slot selection, same 
dimensions as a long disk controller. Mostly useful under OS/9 but I 
seem to recall it worked under DECB to allow a RS-232 pak & disk 
controller to be used simultaneously & the 3rd slot prevented beating 
on your CoCos expansion port when using ROM games. The buffering 
allowed the use of Y-cables too, AFAICR.
