Thanks, Gene.  CoCoNet doesn't use interrupts with the 6551 for the 
virtual drives.  In fact, no hardware handshaking is required.  I 
remember being dragged down a road by my very short hair over 
something like a CTS/RTS issue or what-not even as I explained that 
none of that mattered.  I feel confident that the limited serial 
circuit of the 4-in-1 board will work just fine for another 
high-speed virtual drive connection.  I was just wondering how many 
people actually own and use those things so I can make some decisions.
