I am sure there is no compatibility. The VT220, etc keyboard (LK201) interface is a 9600 baud asynchronous serial port. The VT100 keyboard has a single bidirectional data line, which something tells me carries clock and data. It would of course be possible to make an interface between them, or to make a VT100 compatible keyboard from scratch (schematics are in the VT100 printset and the keyboard is all standard ICs, including one of those dumb 40 pin UARTs). But it's not just a cable adapter. -tony
