Also, and this is related to the above, can we do more of a true HHKB (6.25 spacebar) with a 1.5x/1x to the right, thus making it look identical to an HHKB? Again, after looking at the PCB and universal Plate, it looks like it would work to me, but would probably require a Universal plate.
Edit - Errrr I guess there will probably be a problem with the stabs moving left and right making them not very stable lol. So no HHKB w/ 6.25 spacebar hmmm decisions decisions
Actually, the "exactly 100% true" HHKB layout is this: (1.5)-1.0-1.5-6.0-1.5-1.0-(1.0)-(1.5)
These switch positions are supported by the PCB. The 6.0-unit spacebar has an offset center stem, so that it uses the switch position for the 7.0-unit spacebar.
However, I don't think the spacebar stabilizer holes exist on the PCB for the 6.0-unit spacebar's outer stems. I'm not totally sure about that, but I will check it in a bit and edit this section accordingly. Edit: The stabilizer holes for the 6.0-unit are basically a hybrid of the 7.0-unit spacebar's (left and center stems) and the 6.25-unit spacebar's (right stem). So you can actually make this layout work without a plate, or with the Universal plate (I think) with PCB-mount stabilizers.
There is currently (that I know of) only one case design that implements the blocked ends on the bottom row to replicate the HHKB design, and that's WFD's case. It would be up to him whether he wanted to change the design of the case top and plate to incorporate the rare 6.0-unit spacebar for a 100% true replica, or stay with the current design which utilizes the much more commonly found 7.0-unit spacebar. And (to my eye) fixes the asymmetry of the HHKB's bottom row.
For everyone else besides Jocelyn and jcrouse, don't worry, nothing has changed. Continue to place orders. No need to worry about this. It was posted as an FYI. Anyway, it's TL; so DR.
