I was looking through Goodwill when I found this, the switching mechanism was pretty awful and mushy KeyTronic rubber domes, however I noticed the barrelplate was a separate piece and wasn't curved like some rubber dome boards with separate barrelplates, so I figured it would be fairly easy to make a mechanical interior. These boards are fairly common on Ebay as well, plus there aren't many Alps boards around with media keys so this would be fairly unique.
The only thing a bit weird about this board is the profile of the case, probably similar to that of an AEKII with an insanely tall f-key row. The original keycaps had longer stems to compensate, so I'll probably 3D print stem adapters or something.
I'm working on a PCB next.
