Recently, I finished installing an Orihalcon/Soarer internal USB converter and panel-mount micro-USB connector in a Zenith Z-150 keyboard (black label 84-key XT-like layout). This is the version with SKCL green Alps switches and dye-sub PBT keycaps. However, I put the Zenith dye-sub PBT caps on a LE DC-2014 blue Alps board, which has almost the same layout as the Zenith. So, I am typing this on the Zenith with doubleshot ABS caps from the DC-2014.
The XT-like layouts on the LE DC-2014 and the Zenith Z-150 are actually not bad at all, and they lend themselves to remapping to a HHKB-like layout. For example, there is a short Right Shift with a */PrtSc key to its right that serves nicely as a Fn key, and the elongated Right Bracket works well as a Backspace.
I have had a bias toward clicky or tactile switches, and I didn't expect to like the linear green Alps. However, I do like them. They are extremely smooth. The Zenith board also feels very solid; it doesn't have a hollow plastic sound like the LE DC-2014 (although I like it as well -- it is "thocky" like my HHKB). On the other hand, I find that I am missing some keystrokes and getting unintentional additional keystrokes, perhaps because of the absence of tactile or clicky feedback. I tried turning on the beep from the internal speaker (Alt+Esc), but I found this distracting and turned it back off.
I am considering doing a click mod on the Zenith, using click leaves and top housings from white Alps switches. If I don't like the result, it is readily reversible. I would like to clean the switches anyway, because I am getting some chattering on some keys, which I hope can be eliminated with cleaning.
