I am pleased to announce that the SIMH AT&T 3B2 simulator now has full support
for the WE32106 Math Acceleration Unit. The change is available in the latest
sources on GitHub[1].
MAU support can be enabled with the command:
SET MAU ENABLE
I'm particularly excited about this change because, at long last, it enables
full support for the handful of packages that were compiled with MAU support
required. That means that the Lucent Y2K patch[2] and the Korn shell[3] now
work properly.
If you have a chance, please give it a test. I am sure there are still bugs,
but I have tried several floating point benchmarks and torture tests to be sure
they behave identically on a real 3B2/310 and on the simulator with MAU support
enabled.
