I have a Victor Branded Fujitsu FKB4700 for sale.
The keycaps are IBM Model M style but I haven't tried to check if they are interchangeable.
This uses the Fujitsu Peerless Switches which is kind of a spring over dome. There is very subtle click to them, but otherwise silent.
The keyboard is fully working . The case is date marked Jan 1989, but that doesn't automatically mean that keyboard was made the same month.
Does not require a Soarers converter; it will work natively with an AT to PS2 to USB converter.
PM me with your offers.
Shipping is 6 euros to Germany. For most other EU countries around 14 euros.
