Yes, I know of few people. They used a self made converter.

That's right. 
AFAIK PC keyboard interface is synchron (uses one bidirectional
data wire) and Sun's one is asynchron (two wires, transmit and receive).

Check this one:

You will find there a rather sparse description of a converter which
should do the job. Although the circuit might look easy it requires
from you some amount of electronic skill. If you don't have it do what
I did: find a friend who has some :-)
Seriously speeking, few days ago I built the converter and yesterday 
evening managed to program the eeprom in the microcontroller.
This morning I gave it to a professional for debugging because it
doesn't work :-(

I will let you know as soon as there is some progress.
