this is mind boggling! although during the 90s might have started to shift to use C in damascene production, but when I was most active (90-94) we were hand rolling a lot of code in assembly. memory "management" was pretty basic at best, code and data occasionally separated. maybe for demos it was less of thing, but for smaller intros, writing into the code during runtime was maybe not everyday process, but definitely not unheard. some of the graphic modes were barely documented if at all, so get this up and running with this accuracy is pretty remarkable. just some of the code from back then, might not pass a PR review nowadays
