I think that date could be pushed back to at least 1995. Here's an article dated January 1996 about SoftWindows, for Mac, which uses phrases like "Mac and PC clipboards", "running PC programs", "playing PC games", and "PC sound cards". https://archive.org/details/PersonalComputerWorldMagazine/PCW%20199601%20January%20Created%20From%20PCW%20Cover%20CD/page/n74/mode/1up https://archive.org/details/PersonalComputerWorldMagazine/PC... Here also is an article about desktop publishing from 1990. https://archive.org/details/FinancialTimes1990UKEnglish/Sep%2004%201990%2C%20Financial%20Times%2C%20%2331242%2C%20UK%20%28en%29/page/n34/mode/1up?q=%22mac+and+PC%22 https://archive.org/details/FinancialTimes1990UKEnglish/Sep%... It talks about "running a Mac-based system and a PC-based system side by side", and how "some text and graphics files can be moved relatively easily between Mac and PC formats". Opposite is an advert for Toshiba's early IBM PC compatible laptops, bragging about winning awards from PC User magazine, which I don't think featured Macs. But when was any Mac ever called a PC? I don't think the Mac Plus, for instance, was called a PC at any point? SoftWindows was Windows bundled with x86 emulator https://en.wikipedia.org/wiki/SoftPC https://en.wikipedia.org/wiki/SoftPC, created in 1986. Note the PC in the name, apparently equivalent in meaning to x86 already. Maybe this was implicitly short for IBM PC Compatible, maybe the term PC was ambiguous back then, and for the next two decades, but I doubt it. (Clearly it is still somewhat ambiguous, though, or I'd have nothing to wrangle about here.)
