I've never seen one.

The workstation card is basically an entire microcomputer on a card.  It
has its own 65C02 (running at 2 MHz, I think), RAM and ROM, plus the
Z8530 SCC chip which is required to get the LocalTalk support.  I
haven't looked closely, but I imagine it is a four layer circuit board.

This would not be a simple task to duplicate.  Another major problem is
that you would need the firmware, and you can't get that legally without
buying the card.

There is also an adaptor box which mounts on the back panel of the
machine, which provides the card with a pair of Mini-Din-8 serial ports.
