Compiler: Looking for older MS-DOS TMS340 / TMS34020 COFF Compiler/Assembler/Linker (GSPLNK.EXE, PREASM.EXE for AXX and others..)

Hello,

For an older project on the TMS340 i'm looking for the (very ancient) MS-DOS install disks of the compiler and toolkit.

(This came with OPUS MAKE and other tools like GSPAR, GSPLNK and PREASM.EXE.)

Does anybody know where to get this? I've looked everywhere and cannot find an archived copy online to download and finish the project :)

Thanks,
