IBM 7094 Emulator now runs Fortran IV compiler

I expect most Dusty Decks readers are aware of alt.folklore.computers, but it’s worth noting Rob Storey’s recent post IBM 7094 Emulator now runs Fortran compiler. As I posted in June, Rob has written a IBM 7094 emulator. Through the work of James Fehlinger, the emulator can load and execute the compiler, and then execute the result, at least for a “hello, world” program.

Rob suggested others might want to get additional programs running on the emulator, and suggested several that are available. Leif Harcke suggested CTSS (M.I.T.’s Compatible Time Sharing System), using the tapes available from Paul Pierce’s collection. I mentioned this to Tom Van Vleck; he took a look at the tapes and lent his enthusiastic support. Rob is happy to make the necessary “hardware modifications” (known as RPQ’s) to the emulator if someone will supply him with a specification.
