Took a moment and fixed the issue with my crashing #Pentium 200MMX system. Now the #PicoGUS with #WP32 #McCake wavetable if running #MonkeyIsland they way it's supposed to run :-) There's also a #Vibra16 card in there, which is unused for this game.

The issue? #IRQ, obviously. The introduction of a SATA controller meant that IRQ 5 previously used by the PicoGUS was grabbed by the controller and the system died with playing audio.

Nice to know the tech skills of the #90s are still there.

And sorry about the video quality - I got all excited and didn't care.
