Mention was made of putting transistors in backwards, i.e. exchanging the
collector and emitter.

High beta , i.e. =< 200, will work as transistors either way usually.
NPN becomes PNP and the beta drops to around 10 or so.




Although curiously interesting, this situation can cause copious confusion.
