At the time Mac Classic was relevant, PC still wasn't thar great in home computing, no one was bothering with this stuff in x86/PC.
We were still bothering with demoscene stuff in 8 bit home computers, and those of us busy with 16 bit home systems were focused on Atari and Amiga systems.
PC and x86 at home only took off, meany really taking off among demoscene and other home users, was when VGA and sound cards became part of a standard PC.
The Mac Classic was released in 1990, the Mac Classic II that is the subject of this article was released in 1991. At that time PCs with 286s and 386s were already common, and the 486 was just starting to gain marketshare at the high end. Most of the undocumented 8086 instructions had already been known for almost a decade; and the majority of those who knew were not demosceners. Many developers used Asm exclusively, and the "classic hacker mindset" was very much alive among them.
Depends on where in the globe one were and in my demoscene circles PCs only took off as interesting after Windows 95, folks using MS-DOS or Windows 3.x were mostly due to their parents family computer.
I think non-x86/non-PC-compatible home computers did remain relevant for a bit longer in Europe and Japan than in the US but by 1992 the writing must have been on the wall.
