It works on NEC system
I am not sure whether it only works on NEC or not
The adaptor for NEC to PC is hard to find .
It is NKRO, PBT Keycaps
shouldn't miss it if ur a realforce fans.
BTW, u can find a lot of them in Japan lower than 50 USD

That is a Sun Short Type keyboard I'm typing on one right now. The converter shown in the picture converts from sun to pc or in this case maybe NEC. If you can get these for $50 us then please let us know where. In the year I was lurking on Yahoo I only saw 3 of them listed true they where not expensive but then again not plentiful either. I would not mind having another one for backup to the one I do have.
