There's the PSC1000 from Patriot Scientific at www.ptsc.com
It's a 32 bit dual stack machine with on-chip stacks and lots of spare
registers as well. Each 32bit opcode in fact comprises 4 x 8bit opcodes
which operate sequentially at full clock speed thus reducing the memory
It's a very clever and unorthodox chip design with lots of features,
including all sorts of memory management stuff and a separate on-chip
I/O processor. Unorthodox frightens some people.
It's also inexpensive, low power and very fast. Patriot supply C and
Java, and Forth Inc supply - you guessed it - Forth. The instruction
set maps very well to Forth's virtual machine, making it almost an
*actual* machine. Forth frightens some people.
The documentation is good quality and in .pdf format. Be bold.
