@p @MisterRogersSnapped >I'd like to be able to get an old Hercules video card for it, amber monochrome monitor, complete the experience
https://github.com/viti95/FastDoom has Hercules video mode, though because of all the realtime dithering it might require more power than a contemporary machine with VGA-compatible adapter, so something like very late boards with ISA slots that took P3s or Athlons.
>what the 90s looked like
Honestly, I think defining an era just by a decade is a misnomer, technology in, say, '92 was quite a bit more primitive than in '98. The early Web era was between the PCs getting cheap enough for home users and the dotcom bubble burst, so around 1996-2002.
