In this case, it's not a weirdo, is it? I don't know of any popular ISA with a stack that grows upward.

I can't think of any either right now[1], with the exception maybe of very old ISAs where the stack is not in regularly addressable memory at all, and instead fixed depth formed by effectively a bunch of registers. But it might be hard to even define any notion of "upwards" or "downwards" on those.

8051. Quite a popular microcontroller.
