Might be a dual 8-bit latch of some kind... The 66500 board says 'FDU Control' - Fixed Disk Unit? it has addr and write enable switches... looks like a late 70s - early 80s era HP disc I/O - for embedded test - network analyzers - ??? The rest of the photos are so badly lit and out of focus that I can't make out the designations - on the 6119 board - there is a crystal (the oblong tin can) in the upper left corner - above that is some writing - what does it say? Might be some treasures in here - also might be some gold scrap - some of the boards have the 3-RU form factor HP used in a lot of their early-digital era bench gear... Cheers John
