Any PACE users out there?

The PACE was National Semiconductor's first single-chip 16-bit microprocessor. Its architecture was similar to National's earlier IMP-16 multichip processor, which in turn was inspired by the Data General Nova architecture. Godbout designed and advertised a PACE system, and built a prototype, but never put it into production. PACE never caught on with hobbyists, possibly because it was slower than the more common 8-bit processors. PACE, and the later INS8900 NMOS version, did get used in some embedded systems. In May I wrote an assembler and simulator for the PACE, and typed in the published source code for PACE FIG-Forth. I found and corrected a bug in the U/ word. In case anyone actually has a PACE system, I've put the sources online: http://www.brouhaha.com/~eric/retrocomputing/national/pace/figforth/ I'm not quite ready to publish my assembler and simulator, though if anyone feels an urgent need for such things, let me know.
