@lukeshu There are a number of open source emulators available. qemu should be able to emulate the MIPS magnum (MIPS R4k-based) and I managed to run the 2nd edition NeXT port on Previous (https://sourceforge.net/projects/previous/), haven't tested 1e. A Sun 4c Sparcstation 2 is emulated by tme (https://people.csail.mit.edu/fredette/tme/index.html), but that's difficult to build. Working emulators for the Hobbit, Gnot, or Indigo are not available AFAIK. But yes, the PC port is probably the easiest way to run 1e.
