That's kind of what I thought it meant :^( Guess I
really will have to
get the PDP-11/23 up and running if I want to play with this board.
Make sure it is a 11/23, not 11/23+, and make sure it is a Rev.A board
or it too will be looking at BDAL18...

I would think that even the 11/73 CPU would be OK then, as long as you don't
mind living with 248 KB memory...
