I worked with a huge multinational company that was trying to replace the system they used for planning. The system was 10s of millions of lines of 16-bit assembly code written for a minicomputer in the the mid-1970s. The next generation of 32-bit systems in the early 1980s were able to run the code, so they purchased one and kept it running to nearly 2000. They had a project that was trying to rewrite everything in C targeting the DEC Apha, but after 10 years it still wasn't ready yet. Because 80s era minicomputers sucked so much electricity, we were able to sell them new Pentium servers running SCO OpenServer that could emulate them. I always wondered if they ever got their rewrite project finished.
