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.

I am interested; I was a Forth programmer back in the day, but never had a
chance to work with Forth processors.
I am in the Seattle area.
