Not at all uncommon. This area, (Central Maryland, Washington D.C.) used the C-64 in most of their schools. High Schools in this same area used Amigas, later on and many Video Toaster systems!
I can remember seeing an Atari 8-bit prompt on the local cable system's info channel back in the day. Before they went Amiga. :-) I also knew a local newspaper that used Apple ][s for their writers. We sold them Amigas for display ads and the classifieds.
