While idly browsing, I have noticed we have a number of tags whose scopes significantly overlap, and should probably be merged:

There’s also the question of what to do with vs vs . Maintenance and repair are clearly distinct from each other, but ‘restoration’ can plausibly overlap with either, with both, or with neither. This can be discussed under Restoration and maintenance?

    This meta question is probably too broad. But thanks for finding these!

  • @wizzwizz4 Possibly. On the other hand, I didn’t feel like spamming Meta with repetitive questions. Feb 25 '21 at 16:33

    We can have one a week, maybe? That'll last us two months (or slightly under, if that would be a duplicate of this one).

    CPU is a blacklisted tag, and not all microprocessors are CPUs. There are several here that could be synonymised.

  • @Chenmunka Doesn’t seem to be. I just tagged a question with cpu. Feb 25 '21 at 18:50
  • Cpu was deemed a meta tag in the early days of the site. To fully blacklist a tag rewuires staff intervention, we never bothered. The tag has crept back recently. We now have other, simpler, ways of blocking tags, maybe we should.

    A cpu certainly isn't only a microprocessor, unless "retrocomputing" is going to exclude really old hardware and most old mainframes and supercomputers.

    To me, [display] could include things like one-line LED/LCD/etc. displays - e.g., KIM-1 - that are not [screen]. Feb 28 '21 at 5:10
  • @manassehkatz-Moving2Codidact Doesn’t ‘screen’ strictly speaking only apply to CRT displays anyway? A screen is something that shields from radiation, which in CRTs’ case is the electron beam, but LCD/LED displays operate on a different principle. Feb 28 '21 at 7:50

    @user3840170 A screen is something that shields from radiation In a movie theatre, the "screen" is the thing that's reflecting the radiation in my direction. Mar 5 '21 at 0:31
  • @Chenmunka By the way, which microprocessors are not CPUs? I agree with the converse, but this one surprised me. Mar 5 '21 at 16:45

    @user3840170 Think about a microprocessor or a SCSI controller (e.g. the 8085 on the AHA-1542B or the Z80 on the AHA-1542CF). Looking at the whole computer system, they are "processing units", but not central ones. Or go one step further: Chips like the NEC µPD765 are (preprogrammed) microprocessors, but no one calls them CPU at all. Jul 30 '21 at 6:18
