pbuff 3.2 rev E inside layout with C2P1 daughter board

this is the layout I used in my pbuff 3.2 rev E. note there are several main parts missing. no transformer, no Z80 CPU. this will be reinstalled into a new standard plastic case during the restore. the layout will be rotated 90 deg clockwise like the original and the centronics plugs will be flipped upside down to remove the twist in the ribbon inside the case. a db25 will be added for the output instead of directly running the ribbon out between the centronics plugs on the back panel,
