PDP-11/45 Board Issues - test-drb@ccmp.vtda.org

OK, I think I've pretty much decided that it's best to give a shot at
rebuilding the M8108.  For one thing, it's going to be a lot cheaper.  To
this end, could someone email me the prints for this board (or otherwise
direct me to a URL where they can be found)?

   probably the
best move to kludge one of those together, if it's simple
 enough. 
 No, it's a hex height card with address buffer chips on it. The schematic
 is not that complex, but the board is not just connections. 
OK, unless it's really simple, I guess that's out.

...
   Memory
management is not all that important to me. 
 It will be if you get any peripherals and want to run an OS. 
Granted, but I think that's a long way off.. :-(

Thanks,
