Me too. I still use an old Cherry mechanical Keyboard, with an Adapter from DIN-5 to PS2 and WITHOUT Windows keys. Must be almost 20 Years old that Keyboard and I've got it for free from a friend. Indestructable, these Cherrys and very heavy and stable. Only downside is the missing of Key-lights but I guess this is not possible with oldschool mechanical Keyboards.^ I still use a keyboard with a DIN-5 connector
Actually not being able to press more than a few keys simultaniously is called blocking and not ghosting.
Both effects are not caused by the usb spec though, but by the matrix of a keyboard, that can only allow a certain amount of keys in certain rows to be pressed or else they cannot be processed (blocking) or there are some other keys registered even thought you don't press them physically (ghosting).
Blocking can also be a limitation in the keyboardencoderchip.
Could a keyboard be logically two keyboards, two usb devices, and therefore double the number of simultaneous keypresses?
