Extended Use of the CAMAC Dataway

A study Group of the ESONE Committee has been exploring possible ways to extend the use of the CAMAC Dataway (1) in a manner that will maintain compatibility with existing CAMAC hardware. Major areas having attention are greatly increased addressing within a module, handshake timing on the dataway and a mechanism to allow Auxiliary Controllers to address modules in other crates. These extensions will allow those users and. manufacturers who already have a commitment to CAMAC to better exploit new devices, such as large RAMs, that are now available. This paper describes the objectives and the present progress that has been made.
