Ok this is pretty much a shot in the dark, but I'm looking for a specifc assembler/linker toolset from 1985/1986. It output shows this header: PROASM-II Linker Ver 2.05 (c) 1985,86 by IWASAKI/K.M.C. I suppose it is part of a package that has assemblers for different CPU, including IR80 for the assembler. I am looking specifically for the Linker which I think is called LNK.EXE. Any version would be nice.
PROASM-II is still made by Kyoto Microcomputer Co. Ltd. (K.M.C.). Have you spoken to them? The DOS version is 98,000 Yen (730 Euros) + tax. http://www.kmckk.co.jp/proasm/
