====== Micro Process Controller ======
The Micro Process Controller is a unit by [[qlwiki:DiRen]] with 6 switched relays, connected via a parallel interface (or serial to parallel converter) with a through port for a parallel printer. 


The switched relays allow you to control other electrical equipment, such a as lights, radio, or even time sensitive photographic control.  Controlled by the computer, this allows speed of switching to be set from micro-seconds to days.


Two units could be connected in series if no printer is used. Each relay could switch up to 240V AC at 3 amps and easily controlled from BASIC. 


The MPC unit was contained in a small black box and powered either by 9V battery or external 9V 250mA power supply.
