All this text, yet nowhere its mentioned whether it runs Doom. Clearly the most important thing to run on any device
OG Doom does not support (or need) hardware 3D acceleration. It's not a polygonal rendering engine.
Relatedly, and probably not to anyone's surprise, this is why it's so easy to port to various oddball pieces of hardware. If you have a CPU with enough clocks and memory to run all the calculations, you can get Doom to work since it renders entirely in software. In its original incarnation -- modern source ports have since worked around this -- it is nonsensical to run Doom at high frame rates anyhow because it has a locked 35 FPS frame rate, tied to the 70hz video mode it ran in. Running it faster would make it... faster.
(Quake can run in software rendering mode as well with no GPU, but in the OG DOS version only in 320x200 and at that rate I think any modern PC could run it well north of 60 FPS with no GPU acceleration at all.)
Interesting, learned something new from my silly comment!
Here's a video that explains the limitations of the DOOM engine and with it also briefly how the rendering part of it works (from 4:08 onward) in a very accessible manner:

If you want a more in-depth explanation with a history lesson on top (still accessible, but much heavier), there's this excellent video:
