Some, such as writing directly to video memory became widely accepted, and [ALMOST] all manufacturers made allowance for it. But, there were some programs, such as "Flight Simulator" that wouldn't run on a lot of machines. (Note: by the 1990s, versions such as the "crash into the twin towers" (where do you think Osama got the idea??) had solved most of the incompatabilities. And, some copy-protection schemes were too sensitive. And, some was deliberate - my publisher (may they Rot In Pieces), in order to try to make a pitch to IBM, had me create a version of Xeno-Copy that would fail to run on anything other than the actual IBM machine. But, then they screwed up and sent THAT out to magazine editors, and it ended up being used in 1983 (PC? PC-World?) as "the acid test" of compatability. There were even some idiots who wrote programs on their "Compatible" machines, who failed to ever test them on a REAL PC! along with, "You might experience some minor discomfort"?
