He had said somewhere else that the only difference between the "1" and 2 was the added Mac support. For some reason, the "1" didn't work on Macs.
Strictly speaking, not *only* difference but *main* difference.
The cables appear to be removable. I wonder if they sold different variants depending on which cable came in the box, or whether they included them all...
The cables are removable. I'm not sure if all cables were in a box or not. But I suppose they sold different variants.
I got my HHKB together with PS/2 and SUN cable and the label of my board says just PD-KB01, neither /P nor /S is added. this means these suffix could be seen on boxes accordingly to a cable included.
Setting guide of 4 position Mode sw for *HHKB* seen in
this page is actually for HHKB2. Original model has 2 position switch which defines function of Delete key.
Opt and Cmd icon are printed on Alt and Meta keys on HHKB2 for Mac
All in all, second model is supposed to be superior to original model which was sold only for a year. this may be the reason they listed 2nd model as HHKB in discontinued model page.
I want to examine the box if it says *Happy Hacking Keyboard 2* or just *Happy Hacking Keyboard*.
