This kind of thing is so common. Maybe it was majic in the 1980s. But
now, everything is digital and pre-programmed at the factory.
I have a shiny new Icom IC-7300 transceiver. (That's ham radio talk.) It
has a general coverage receiver, all modes from like 0 to somewhere past
54MHz. But it will only *transmit* on frequencies legal to US radio
amateurs ... at the time of manufacture.
I'VE BEEN TOLD that there is a diode I can clip or remove that will
negate the transmit lockout.
Legally, I'm not supposed to transmit on (e.g.) 870KHz broadcast AM, and
I'm not interested in setting up a pirate station. But hams are into
disaster preparedness. In a crisis, I might *need* to transmit on radio
frequencies that I'm not normally authorized for. (Not to mention that I
hate the whole nanny thing.) So ... yeah ... I might "upgrade by cutting
a wire" soonish.
Not mainframe, but kinda related. And your fault for making me think of
it. *:-)*

Anyone else ever hear this? Can't find a cite on the web.
Just curiosity, no real point to this...! (But it is Friday.)
