[Techtoolslist] What's happening with old 2716/2732

[Andrew Welburn]

I have photographed games running on my bench with the flash on and exposed windows plenty of times. Older games can freak out and crash/reset but there’s never any long term damage. Nintendo weren’t stupid, uncovered windows are not a great issue unless you have the exact wavelength of light for the needed exposure period at the right strength. The reality is in common use you are unlikely to encounter that set of variables lining up to cause damage.

I have these pistols and rifles that use focused strobe tubes to illuminate CDS cells on their targets for a large scale shooting gallery I own on a local midway (Pacific National Exhibition - Vancouver, BC). So it is an easy thing to fire up - so to speak!
