One of my brothers collogues owns an old Triumphs veteran car which he is very fund of. My brothers collogues asked my brother if he could help him build an air/fuel monitor, originally developed by another Triumph enthusiast called Buckeye (I will put a link to Buckeyes web on the links web page). My brother has therefore produced this very nice prototype printed circuit board and a schematic, take a look at the construction below (click on the picture to enlarge it):
The empty air/fuel monitor pcb (schematic is in the pcb zip file). PCB file updated 2011.05.25.
The air/fuel monitor pcb with all components mounted.  
Simulation of the air/fuel monitor.
