Hi Groups: I have some DEC modules that aren't in the latest Field Guide (thanks to Tim Shoppa for bringing this up to date). The identifiers are: M7684 M7773 M7774 M7776 M7786 M7787 I also have two questions: 1. I have a M7133 Unibus 11/24 CPU. As it's a single card CPU, does it still need a custom backplane, or is this a leter model CPU that can fit in a standard SU or something like that? 2. I have two Dilog controllers, the DQ236 and the DQ256. The Q for Dilog generally indicates Q bus. These have 1 x 60 pin header and 4 x 26 pin headers on them. Disk controllers? What type of drives? Any info appreciated, Kevin -- Kevin McQuiggin VE7ZD mcquiggi(a)sfu.ca
