I know that it is still on the go but I had not heard of Voltage 
Contrast. Not surprising as it is about 20 years ago that I last worked 
as an engineer.* And almost 40 years since I worked at Motorola's chip 
factory in Scotland.

I did the maintenance on the testing equipment.

* I did get my soldering iron out a couple of days ago to repair 
something. Ah! memories. :-)
