Not disputing anything, but I'm curious about early examples of
network interfaces and multitasking OSes for machines which were
typically designated as "toys".  Color, sound, graphics chips and
alternate input devices are obvious candidates, but aside from
OS-9 for the 6809, I'm drawing a blank on the other two.
