Is dosbox being used as an example, or was that actually the emulator? I find this intriguing. I would've assumed PCem or MESS was a better choice for writing a demo for something like an XT computer. Dosbox is useful but it definitely hits me as something that is emulating a software library per se, and only the hardware as an accident of that, a valid approach that is a lot less useful for programmers working under it...
I used the DOSBox debugger to debug several of the effects during the making of Area 5150, but other than that I used real hardware. 86Box is probably the most accurate one at the moment but still isn't accurate enough to run the entire demo correctly.
Given that the demo targets AT-class hardware, it is unlikely that something like PCem or MESS was used, because in those cases you'd actually have to select an AT-configuration to make it work, instead of an XT-configuration.
DOSBox does not have this option, it always emulates AT-class hardware, in which case this demo 'just works'.
