I am still trying to track down the Motorola structured assembler for 68000. I found another lead in a 1983 Motorola software catalog. Motorola had the assembler, linker, and Pascal compiler available as "Pascal source code for the IBM 370 with Pascal VS2 on 9 track tape" (but the requirements said "any operating system with FORTRAN"). Do any big iron folks have this? Paul R. Santa-Maria Ann Arbor, Michigan USA paulrsm(a)ameritech.net
