I have a really compact "PDP-11/23S" chassis that has an 18-bit Q-Bus backplane (4xQuad) in it. Although the circuitry for the Q-Bus is on traces of a PC card, there are also wirewrap pins extending out from the backplane. Am I naive to assume that I can convert this to a 22-bit Q-Bus by wirewrapping four or so lines? Any pointers on how to do this or on technique? Thanks, Dave
