Oh, I agree with you there. Things get even worse when you go to the 11/73 family - there at least three dozen different boards all based on the same J11 chipset that's in the 11/73. And some of those boards are identified by DEC as 11/73's if used with non-PMI memory, and are identified by DEC as 11/83's if used with PMI memory! And within a given board etch, there are different designations depending on the rev level of the J11 chip installed and the frequency of the crystal that's installed. -- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology WWW: http://www.trailing-edge.com/ 7328 Bradley Blvd Voice: 301-767-5917 Bethesda, MD, USA 20817 Fax: 301-767-5927
