This is sooooo totally late in a reply. But you never know.
I have a PCV-W20 unit, and the full set of restoral disks. Are you still interested?
By the way, I recently ran into alittle issue myself, although hardware related. It turns out the key caps on the keyboard are made of exreamly cheap thin plastic. I moved my computer in my office next to a window which gets sunlight.
Guess what… now some of my key caps are deformed.
Do you know anyone who has any of the matching model units that don’t work and may want to sell parts off it?
Thanks
