To bad the parallel port has also gone the way of the serial port.
I've used the parallel port with a paper tape reader that had
a parallel out. One needs a bidirectional port, connectors and wire.
It allowed me to save a lot of tapes that were borrowed.

The original key board ( although nice ) is just a parallel out keyboard.
Most any such keyboard would work ( may need strobe inversion ).
If you don't have such a keyboard, you could probably write a trivial
program for an old-ish PC compatible to read characters from its keyboard
and use 9 outputs on the parallel port (say the 8 data lins and Stb/) to
provide the parallel output to the MDS.
Yes it would be a kludge, and you'd probably want to make something
smaller and simpler for use, but to get the machine working it would do.
