Even though I included the serial# of my >distribution, I didn't get any response. Microport will not give you doo doo on this, I called a long time ago and tried to get even a simple table of opcodes which were implemented, no luck. The best thing I have found is the combination of compiling various C programs with the -S switch and see what type of assembly output is generated, and running various .o modules through "dis" (which is undocumented anywhere I have looked). If you find a source which has good details on this, please drop me a line. -- Mike Mitchell BELL: (505) 471-7639 2020 Calle Lorca #43 ARPA: mdm@cocktrice.UUCP Santa Fe, NM 87505 UUCP: ...!uunet!dmk3b1!cocktrice!mdm
