[rescue] ADB <-> PS/2 Conversion

[Torquil MacCorkle, III]

Does ADB <-> PS/2 conversion require some sort of circuitry besides just
rewiring? (DIY possible?) I'll assume so as they seem to be ridiculously
priced?

Also, can I use a serial->9pin PS/2 adapter and a mouse and some kind of
USB->PS/2 converter for a keyboard if ADB conversion doesn't work out?

(I am trying to setup a PeeCee and a G3 to share a 2 port mechanical KVM.
