SNES consoles appear to run faster with age — APU frequency increased by up to 182 Hz after 35 years
(www.tomshardware.com)
This is a most excellent place for technology news and articles.
Ceramic resonators have a typical accuracy of +/-0.5%. An error of +182Hz is a +0.57% error rate.
Here is a datasheet cited by the Wikipedia article. It says 0.5% initial error, another 0.3% over its full temperature range, and another 0.3% over 10 years of aging.
I guess "SNES operating within spec after 30 years" doesn't grab attention the same way.
