Someone mentioned the 68HC11 chips. Those were EOL a while back and the
remaining ones out there are existing stock. They have a new chip that is
code backwards compatible 99% (there are a few things that the new chip
doesn't have that the old one does) and I think that the new chip is a 3.3v
device as opposed to 5V device. (the site controller and door controller
devices I have been repairing are 68hc11 based and are no longer produced
because the company that was making them was buying their chips from a
supplier in thailand that got flooded out and one of the casualties was a
huge stock of 68hc11 ic's :( )
Technically,
the 6502 isn't still being manufactured.
Technically, many of these older chips may not actually be manufactured
anymore, and are available only because of stockpiles in warehouses.
