The SPARCseries 300 machines come equipped with both "double-high (6U)" and "triple-high (9U)" VME slots. In the latest Catalyst catalog, a great many 3rd party VME hardware products require a "double-WIDTH to triple-WIDTH VME adapter board". Q1. Are "double-HIGH" and "double-WIDTH" synonymous? Likewise for "triple-HIGH" and "triple-WIDTH"? Q2. Does the Catalyst requirement mean that (a) the 3rd party product is equipped with a double-width interface that needs to be adapted to a triple-high VME bus on the Sun, or (b) the other way around? Q3. If the answer to Q2 is (a), does this mean that such a product would connect directly (i.e. without an adapter) to a double-high VME slot on the Sun? Likewise if the answer to Q2 is (b)? I promise my first-born child to anyone with the (correct) answers. Patrick Goebel--romeo@lindy.stanford.edu CASBS--Reluctant SysAdmin
