LK201 emulation

[Electronics Plus]

Do you guys want original LK201s, or other keyboards that LOOK like LK201s
in the caps and layout, or converters?
I am a little confused...   LK201 clones do not have the clip offset on the
terminal connector, so you would have to replace the connector. I have no
idea if the protocol, voltage, etc is the same.

I would absolutely be interested in this - while I'd love to use original
hardware where possible, it's not always easy to get peripherals at the same
time as machines. A long term dream of mine is to build some sort of
general-purpose box that can make connections to arbitrary vintage computer
keyboard/mouse/video ports, and connect in to modern HDMI & USB peripherals
to make it easier to just pull a machine off the shelf and get going.

an adapter that connects to a standard PC USB keyboard and makes it look

an amazingly tiny yet powerful small microprocessor).

and parts list.  I don't think I want to get into building units for others,
though.
