Forgive me if I wasn't clear -
My point was that instrumentation buses outlive computer 
buses. I don't think that anyone should start with the 
oldest instrumenation bus that they can find.

With regard to putting real-time into home-grown hardware, 
please see all of the devices around the globe that are 
not supported as they were home-grown and the designer is 
no longer around. I really see this as a last resort.

A number of spares for bit-bus would have been helpful. 
Today, it seems a good bet to put anything you can on the 
ethernet. The protocol to talk to the device may not be 
standard, but the transport over the wire is. Bit-bus did 
not share the same popularity. I think the lesson is to 
choose instrumenation buses that are well supported.
