RingabelThe switches are compatible but be careful because the keycaps are notoriously difficult to remove. I replaced my 'esc' cap and was afraid I would pull the switch off the board.
Ringabelpartly. you will have problems with the bottom row - only the option keys fit this board properly, even the space bar from the AEKII is slightly larger and the stabiliser mounts are not compatible. it's best to order a vintage one, so you can keep the original bottom row. until we get PBT switches from matias, that is your best option.
dmichelinhow's the typing feel on those alphas? apple like ibm curved the switch plate instead of the caps, right? (edit: fixed typo) it looks flat in the pic, but i'm not 100%. (just curious cos rn i have dsa caps on bc i like the flatness, but also enjoy alps-type switches)
dolljointsThe typing feels really nice on them, it's especially nice as it is difficult to get ahold of PBT keycaps for alps switches. They curve much more subtlely than do the base keycaps on the board, but I don't really notice the difference all that much.
