I'm looking for a keyboard thats bigger than full size/100%.
I understand that keyboards such as Hyper7 and the Boston Compact exist. But, I want to know if there's more than those two. I've searched everywhere and other than these two there's no information on people looking or owning a bigger than normal keyboard other than the aforementioned.
Also, if possible, a marketplace to purchase these.
