1) What color keys come in two piece (2pc) with a cap and stem and which do not?
a) Standard/Stock (which is pearl white and beige?)
b) Metallic Grey
c) Pebble Grey/White
e) Black
f) Others?
With Unicomp you are never really certain. Any given board may have an arbitrary mixture of two-part and single-part keycaps. As far as I know, the black keycaps are usually always single part.
2) What colors and keys go with themes?
a) Perl White
b) Raven Black
c) Black with metallic gray
Black case with metallic grey keycaps and white case with white keycaps are the standard options. Black on black is non standard, and the black keycaps are always blank.
What is the diference between the "SpaceSaver M" (UB4ZPHA) and the "SpaceSaver - M"
(UNIZPHA)?
Colour as far as I know. Both are Mac keyboards.
3) Can a pointing stick easily be removed from the Endurapro?
Yes, but it's hard to reinsert (you'd end up breaking the clips while removing it). You'd be better off buying the Spacesaver which is just an Endurapro minus the pointing stick.
4) Can a pointing stick easily be added to a SpaceSaver104?
No. The casing on the Spacesaver doesn't have the cutouts for buttons (although you can see on the case where the cutouts would be)
5) Does the Endurapro and Spacesaver have the same controller board?
For the keyboard itself, yes. The Endurapro has an additional controller board for the trackpoint. The controller for the keyboard is also hooked up to that controller, and the cable to your computer, either USB or PS/2, runs from the trackpoint controller.
6) Is there a chance for a Mini in the future?
(The banter and jokes in the forum on this topic is confusing me.)
According to my Magic 8 Ball - Outlook not so good.
7) Are some keys just not available as 2pc?
Anything that isn't a single sized key, or a Tab sized key.
What are the differences between the SpacesaverM and the SpaceSaver104?
a) firmware (specifics?)
b) keycaps
c) other
As far as I know - Firmware. It sends different scancodes for the Apple-specific media keys, so it would have to be different to a PC keyboard. It has some different keycaps too.
9) Can the user easily load firmware?
No. It has never been done as far as I know, nor is it supported.
