Wow. Nice Apple collection! That lot is a treasure chest for Apple collectors. Each board is a classic Apple keyboards of significance and is mechanical. (Alps)
The compact board looks like a Apple Desktop Bus Keyboard. It was the first one with ADB protocol and came with the Apple IIgs.
The Apple Extended Keyboard has clicky Alps. Most Apple Extended Keyboard II have dampened "Cream" Alps, but some have other switches. Matias' keyboards are like modern clones of these boards (Tactile Pro and Quiet Pro respectively)
The Apple Adjustable Keyboard has low-profile Alps keys. Too bad that the separate numeric keypad is not included.
I would definitely have bid on them if I was in the US. Overseas shipping would be too much for me.
Good luck to the bidders!
