It's actually a very rare kind of keyboard no longer being manufactured.
Unlike most keyboards, the PLUM keyboard organizes keys in a square grid, as opposed to the staggered rows of a typewriter.
It also goes up to the F15 key.

Plum is a town in Pennsylvania. Most of the kids that go to plum are snobby bitches. To be fair though, not all of them are like that. But some are annoying af. The boys that go to plum are terrible at relationships and just talk about how “thick” their wieners are. If you date a plum boy and break up with him, they will most likely end up with someone else the next day. That is because the people who go to plum are usually desperate which makes it easier for people to find my relationships.

But those are just the cons of plum. Plum is a good fruit that taste really good. The plum girls soccer team is pretty good. We will give em that.
Oh, your from plum. I think we should break up and never talk to each other again.

Sorry, I don’t speak plum.
