OK, so this is a simulator, not an emulator.

But I still wonder why the comment re. the diagnostics program said...

...that a real HP67 does something wrong in that it rounded the result incorrectly. This is not true – the 10-digit value 1.111111111 E+88 times –8 is exactly what's displayed: –8.888888888–88.

Willy, are you out there? If it's you who wrote this, could you please explain why you think a "real HP67" is wrong here? Maybe I didn't understand you correctly.
