RTX-2000 processor PC/AT add-in card (any takers?)

I have a Harris RTX-2000 based system control board for a long defunct system.  The board worked when removed more than 20 years ago in the mid 90's.  The RTX-2000 is a stack-based processor designed for running FORTH.  I think it was designed by Phil Koopman based on his graduate work.  The board is a 16-bit ISA board.  It was part of an MRI system that ran a version of MPE forth with a C-to-FORTH compiler (actually a C-like variant) that spits out a 16-bit FORTH variant with some embedded RTX-2000 code.

I also have another card with 3 channels of streaming 16-bit digital I/O, with special hardware to implement on-the-fly rotation matrices to the streaming output.
I have all the software and drivers as well. and I have written a c-based simulator that can run the FORTH/assembly emitted by the C-to-FORTH compiler (as well as the MRI libraries and hardware.)
If anyone wants to tinker with this hardware, or just pull the RTX-2000 chip, I would rather find a good home than toss the boards.
