I went to a well funded school in New England, this was period correct even as late as 2013. For VHS especially these carts were still in use, but starting in maybe 2007/2008 some teachers would use their computer + VGA projector setup for DVDs. Especially since there weren't enough carts to go around
lol maybe, VCR's are a bitch to service though. It probably would have been cheaper to replace it. I have no basis for that, just guessing. Feel free to call me out.
