DEC Qbus Replacement Controllers

Your PDP-11 or MicroVAX is a workhorse, but what do you do when a controller fails and replacements are no longer available?  Digital/HP no longer offers spares for some Qbus controllers.  We may be able to help.

The Logical Company uses leading-edge technology to re-design the old, familiar but obsolete DEC controllers for the Qbus.  Our controllers offer a fresh start – a new controller with pin and signal compatibility with your existing DEC controllers, plus a one-year warranty
