I think you're confused between terminals and keyboards.

LK201 keyboards don't have offset clips (MMJ connectors).  Instead, they use a standard telephone handset connector. 

What I was talking about is a way to use a PC USB keyboard in place of an LK201, when your last remaining real LK201 has just failed.  That involves a USB jack, a LK201-compatible handset jack, some electronics, and software to speak the protocols involved.  That's what I have just prototyped.
