Just another program poking memory it’s not supposed to. Not even necessarily maliciously.

That AmigaDOS emulation will almost certainly never run another program. (-:

Far more concerning from a RISKS point of view is the spare parts being physically in the same place as the live machine.

What other program? Most DOS versions were not multi-tasking beyond "terminate-and-stay-resident" (TSR) programs like mouse drivers.

Whatever application you ran on DOS was THE application your computer was running.

We're not talking about DOS here. This is AmigaOS, a fully preemptively multitasked OS from day one. No memory protection, but unless your code is running on bare metal like demos and games, there are other tasks running.

Top parent of this thread is talking about a package for AmigaOS being run on a bespoke emulator (as the Unusable Amiga Emulator of the 90s wasn’t really a thing that could be used for that)

Bit flips from cosmic radiation. Pretty common.
