Ladies and gentlemen, boys and girls, children of all ages - I present to you LambdaDelta, my decidedly average LMI Lambda emulator.
See https://github.com/dseagrav/ld for the source repository and release tarball. So far we have been able to run full-speed on a 2.3 GHz i7 and a 2.5 GHz i5, but the i5 was pushing it. The i7 gets a bit warm. Bitsavers now has the LMI software, so there's no reason to hold off on a release other than I would have liked to get fetch working properly at least. I'm going to keep working at it in the meantime.
