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.
