He points out that you can still buy CAMAC hardware,
but how much CAMAC hardware are they using at the SNS?
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.
