Even the original Intel 8051/8751, circa 1980, has security

What do people
do regarding microcontrollers (old or new) with
embedded ROM? I
mean an EPROM or PROM's just address lines and data, so reasonably
easy to
dump - but presumably life's a bit more difficult when the ROM is
local to the CPU...
If you're lucky, eitehr th microcontroller is old enough not to
have any
security features, or they're not used. In which case you remove
the chip
from the PCB and stick it in a suitable programmer.
