For the sake of transparency, here's the answer that I unilaterally voted to delete:
When I had to move from New York in 1995, I chose to not take my S-100 nor its two eight-inch drives.
That is the answer in its entirety, answering the question:
Did personal computers ever support 8" floppies?
I mean, it does sort of provide some information that could perhaps be used to deduce that the Altair 8800 could be connected to an 8-inch floppy drive, but... really? I had to use both knowledge I've absorbed from this site and three different web pages to figure that out. If you'd provided more information in your answer then perhaps I wouldn't have deleted it, but you've used over 2.5x the number of words in this question than in your answer!
And now I'm going to tackle a few misleading parts of your meta question:
so obviously stating that mine did IS an answer to the question.
This is a true statement, but it implies that your answer stated that your computer had two eight-inch floppy drives. It includes that information, yes, but the focus of the sentence (the entire answer, even!) is on you moving from New York and not taking your computer.
But why claim the obvious isn't there
It's not obviously there; the only mention of an 8-inch drive is in the final three words. And for all I knew, the S-100 could've been an IBM mainframe machine, or perhaps a terminal; there was no context to say that it was a board included in personal computers and not something other than a personal computer.
By all means feel free to improve your answer, and I'll vote to undelete it. But the answer you originally posted was... not really an answer at all.
