Hi Dave:
The easy way to tell a quad pdp11 board from a quad
pdp8 board is to look at
the top and see if it's got metal ejector handles or plastic "flip chip"
style
handles. pdp11 boards have a metal spine and metal ejector handles, pdp8
boards have the plastic handles.
This isn't the case. There are several quad height Unibus/pdp-11 cards
that have plastic handles! Check the field guide or ask on the list!
