I guess if I were teaching a young 'un, the AVR would be a good
choice. Part of the problems with PIC architecture lies in the way
said architecture is described in the datasheets leading to some
warped thinking. But the other part does lie in the warped
I think discussion of the PIC is probably on-topic, as the
architecture dates back to 1975 as a support processor for the GI
CP1600 CPU (which had a much more orthogonal instruction set).
Of course, the 8051/8048/68HC11 all qualify as vintage architectures
and would also be choices for teaching.
