Emulating the AT&T 3B2 Computer

But Lucent already has a 3B2 emulator.[1] It's used to run MERT and DMERT, real-time operating systems used by central office phone switches for auxiliary functions.

My guess is that:

1) It's not open source / FOSS

2) According to the linked article, laced with bugs

3) Only runs on SPARC

edit:

4) Not using SIMH

Oh, come on, you can emulate a SPARC using qemu! ;-)

Or with the TME emulator (https://people.csail.mit.edu/fredette/tme/).

Also, 5) it's a 3B20, not a 3B2.

Lucent's emulator is for the 3B20D, a very different beast from the 3B2/400. They use the same CPU set, but have a different system architecture.

But the bigger problem is that Lucent's emulator is not open source, or even widely available. You can't even legally get the binary as far as I'm aware.
