Let's move this to a new thread subject of its own !

Another now-defunct company, Microtec Research Incorporated (purchased by Mentor Graphics in late 1995), definitely had a TI9900 cross assembler written in FORTRAN from 1983.  We had the source code under license and compiled it under VAX/VMS (complete with CLI switches), and with a few custom tweaks, it was largely compatible with SDSMAC that ran on TI's 990 computer systems (now simulated via Dave Pitts' SIM990).  There was also a linker/loader that produced Tektronix HEX output (similar to TI's SDSLNK) as the final executable.  I was able to modify the code enough to get it to compile under OpenWatcom's Fortran 77 on Windows XP.
