  I'd be very interested, not because I have a shortage of DEC keyboards or
mice, but because it'd allow me to use my VAXstation or PRO-380 on a KVM
switch along with various PCs.  The KVM switch can handle the video, but it
can't cope with the DEC keyboards and mice.

  I suspect that this may not be as easy as you think, but if you're serious
I'll build the hardware if you write the firmware.
