A few comments mention how trivial this must have been to bypass; yes with today's internet, youtube videos, online tutorial, open-source hardware and the ubiquitousness of technology in general, of course this seems trivial.
However, in the context of the 80s, this was far from being trivial; there was no internet, no google. It probably didn't even occur to most people they could try to bypass this, and even if it did, who would they have asked?
