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.
