I used to use write protect tabs.
But aged write protect tabs rarely still stick well.
And, it is a hassle to dig out ones that have fallen off inside the
drive. I ran most of my 8" drives without cases, so it wasn't such a big
deal.
Neither were especially common, so the combination

I use an 842 here quite frequently, and as far as memory serves, it's
side-hole-blind. That is, a disk with a single-sided aperture only can
still be processed as a double-sided disk.
However, as Fred says, best to check the jumpers. I believe that Al has
