[HECnet] Off topic... MAC80 10B(112) 8085/Z80 Cross Asembler

I have the EXE file for a 8080/Z80 cross assembler, but can't find the sources.. Anyone have a pointer? It says "MAC80 10B(112) 8085/Z80 Cross Assembler" on the listing output MAC80.EXE.1;P775252 19 9728(36) 29-Nov-1983 It's a "tops10 program"... It can do both 8080 and z80 mnemonics, and the sources I have named mac80 can only do 8080, and they start like this... ;MAC80 - An 8085 cross assembler for the DECsystem-10 ; Copyright 1976,1977,1978,1983 ; Bruce Tanner / Cerritos College ; 11110 Alondra Blvd. ; Norwalk, CA 90650 SEARCH M80UNV,MACTEN TITLE.
