The CP/M-68K 1.0x source distribution at
http://www.uxpro.com/cpm/www.cpm.z80.de/source.html includes a VAX/VMS
distribution of Digital Research's 68K cross development software for
VAX/VMS. After unpacking the source distribution, look in v102/cross for
that distribution. Excerpt from v102/cross/install.doc:
This document describes the installation and execution
procedures for the Digital Research 68000 cross development
software for VAX/VMS. This software includes the C compiler,
assembler, linker, archiver, symbol table print utility, object
module size utility, and S-Record conversion utility. These
tools execute in much the same fashion as they do under CP/M-68K,
as documented in the CP/M-68K Programmer's Guide.
