That sort of thing was done in the 1950s. -- Shmuel (Seymour J.) Metz http://mason.gmu.edu/~smetz3 עַם יִשְׂרָאֵל חַי נֵ֣צַח יִשְׂרָאֵ֔ל לֹ֥א יְשַׁקֵּ֖ר

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. *:-)* -- R; <>< On 5/31/24 9:49 AM, Phil Smith III wrote: > I remember hearing that some Amdahl 370 clone was upgradable by cutting a > wire.
