MIT CADR Emulator

mit cadr lisp machine emulator screenshot

Brad Parker has a booting emulation of an MIT CADR Lisp machine (a commercialized CADR was Symbolics' first product, which they called the LM-2)

I've been working on a emulator of the MIT CADR. Basically a program to run its microcode. It is now running to the point where it runs a load band. There is basic display, mouse and keyboard support. There is some code for the chaosnet interface but it's not (yet) wired into the real network

The README claims the emulator is 90% complete. Source code is available.

This sounds like systems and computers becoming like the car ralleys at the local drive in. We'll have originals pull up, like TI Explorers, PDP-8s, Commodore-64s and then we'll get the souped up version, made with modern parts but dressedup to look "original":) Humm, PC Mods of a VIC-20 or Symbolics, complete with over-clocked, liquid cooled CPUs.

There could be contests to boot original software, judges from the era picking the winners: "Gee Marvin, this really does feel like Lisp 1.5, what do you think?"
