same old keyboard

[Hiisi]

Dear List!
All photos of the keyboard and the machine can be found at the address

and

They're not low resolution - just click on the image name (link) and 
you'll see the full-size picture. I added there photos of motherboard 
too.
So, re-new my question: is there a way I can run it on my desktop/PC 
computer? If I adapt its plug for serial port (which one, by the way?) 
what are my next steps?
Thanks,
Hiisi

P.S. My mailbox works awful. I can't response. So I decided to start new 
topic.
