Both Retrocomputing and Super User deal with questions about the use and abuse of computers; Retrocomputing deals with questions involving “old” hardware or software, while Super User’s focus is on newer systems. We also have other dedicated Stack Exchanges for some particular computer topics; Stack Overflow deals with programming, Server Fault focusses on server administration, Ask Ubuntu is for questions about (duh) Ubuntu, Ask Different covers questions regarding Apple software and hardware, and Unix & Linux is for non-Ubuntu-or-macOS-specific questions about Unices and Unix-likes, just to name a few.
Problem is, computers (hardware or software - it’s true for both) don’t fall neatly into “old” and “new” categories, but exist on a continuum; thus, there has to be an arbitrary boundary drawn somewhere. Which creates difficulties when trying to ask questions that fall near, or on, the boundary:
- For instance, Windows ME (released in late 2000) falls in Retrocomputing’s bailiwick, while XP, released the very next year, is generally a topic for Super User. But what about Windows 2000 (released a few months before ME, but remaining supported by Microsoft until 2010, while ME left extended support in 2006)? Where would a question about installing XP on a very-late-model PS/2 go? What about trying to run Windows 7 on a computer that originally shipped with Windows 98, or questions about floppy-disk support in Windows 8.1?
- Ask Different explicitly supports, and has questions about, Macs and other Apple products stretching at least all the way back to the original 128k, and the Lisa before it; yet, we at Retrocomputing ourselves have a bunch of questions involving very early Macs, and Apple II questions generally end up here. Where’s the boundary?
- The first Linux versions date back all the way to late 1991, and various Unices already had a long and storied history even then; do questions about these very early Unix and Unix-like OSs belong on Unix and Linux despite their antiquity, or should those early ones come here to Retrocomputing?
Not a duplicate of this question, the answers to which give some general explanations of what is on-topic here, but don't clear up the question of where, exactly, the boundary is.
