I've released an update for mb-audit - an audit for Mockingboard emulation correctness, which doubles up as a set of tests for real hardware to help identify faults:
https://github.com/tomcw/mb-audit/releases/tag/v1.3 https://github.com/tomcw/mb-audit

I've been keeping AppleWin in step with this update, so v1.30.14.1 is the latest that works & passes all the tests.
https://github.com/AppleWin/AppleWin/releases

FYI, the original May'21 thread in cea2 is here: https://groups.google.com/g/comp.emulators.apple2/c/18ozK1FreqU/m/_eBYrGcBAwAJ

I've also bundled some related apps on the disk image:
- play-sc01-using-ssi263 (original Apr'21 thread on csa2p here: https://groups.google.com/g/comp.sys.apple2.programmer/c/F3JfFVOR6pc)

If nothing else, there's a nice tune from 1988 (a ZX Spectrum port) which plays back on the Phasor too (in 4x AY8913 / 2MHz mode).

NB. None of the mb-audit programs work with A2Heaven's MEGA Audio as that card it's missing some 6522 functionality. Tracked here:
https://github.com/tomcw/mb-audit/issues/9

Please report mb-audit issues with *real* hardware here: https://github.com/tomcw/mb-audit/issues

(Or report emulation issues to the respective emulator's creator)

I've released mb-audit v1.42, which adds support for the MEGA Audio card. https://github.com/tomcw/mb-audit/releases/tag/v1.42

Thanks to Andrew Roughan for his help in testing this.
