No, it is a PC USB keyboard.

Hmm. The Sun Blade 100 Unofficial FAQ[0] had an entry from someone  
who said that USB<->PS2 adaptors didn't work for him, but there is  
mention elsewhere that USB keyboards are supposed to work.

Additionally, it doesn't beep when *no* keyboard is attached, either.  
Would that perhaps indicate that the keyboard isn't the (only) issue?

Unofficial_Sun_Blade_100_FAQ.htm, it's the whole thing on one page.  
Clicking the links doesn't work for some reason, but all the answers  
are there AFAICT.
