So do EPROM/PAL programmers exist that are also capable of programming (and

although I've never seen one (but I haven't gone shopping for a programmer in
years)
Thankfully I thought I had something with an 8051 in, but it turns out to be
an 8031, which makes life a bit easier ;)

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 the protection is not set, you can read just like a EPROM
microcontroller. If it is set...well, there are ways, but it is
something hard to do :)
