All I can tell you is that the LK201 interface uses different voltage
levels to the PS/2 interface (The LK201 is essentially RS232 levels with
a 12V supply, the PS/2 is TTL levels with a 5V supply), and a totally
different protocol (the LK201 is 4800 buad async, the PS/2 is, IIRC, a
synchronous interfacem, with clock and data lines).

A translator between them is not going to be totally trivial therefore.
It would certainly need a microcontroller at each end.
