'Equipments' is the default plural in Filipino English. I was appalled when I first noticed it here, but I started thinking it was old-fashioned US English (as much of Filipino English is...). 'Fruits', 'stuffs' and 'cereals' are also used. (As in, 'Would you like some cereals?')

My thinking is that much older English did do this at one stage, and phased out of common usage during the 60s. I have read these plurals in older writing before.

I used to try and explain 'countable' and 'non-countable', but I'm so used to it these days, I'm not even sure how that works anymore...
