You can find the MC68000 board set (you?ll need a CPU board and at
least one memory board) on eBay quite often. In most cases, it will be
the Model 16 6Mhz board which will allow you to run TRS-XENIX 1.x. If
you?re lucky, you?ll find the Model 6000 8Mhz board which will allow you
to run Xenix 3.2. Finding a card cage is the hard part. These are
extremely rare but do pop up from time to time. There is another option
called the Hans-02 and 03 adapters created by Hans Rietveld which is a
modern replacement for the card cage. You can find them on Ian Mavric?s
site.

Correction: You?d want the Hans 03 and 04
In regards to the keyboard, the later Model 12/16B/6000 keyboards are
hard to find. The Model II keyboard is more common. You can easily use
the Model II/16 keyboard with these by creating a new 5pin DIN cable and
switching a few of the keyboard input pins and swapping the gender of the
connector.
