Interesting. Having the old compiler and an emulator is certainly helpful, but of course also yet another complexity. From my experience, it's very useful to have some decently large programs in the target language, the output of which are known. Thanks for the document, I will talke a look at it.

Excellent point. We have many decently large programs. In fact, we have pretty much the jackpot. Ed Feigenbaum famously wrote EPAM, one of the first simulators of human memory. Not only is the program extensively documented in numerous published papers and reports, and not only is entire the code online (https://purl.stanford.edu/vq775jv4844) but if you look at that code, it's actually a compiler output, so it shows us how pretty much every type of IPL-V instruction compiles!
