because on a TI-Nspire, an unstable program can actually damage a calculator permanently.
Quotebecause on a TI-Nspire, an unstable program can actually damage a calculator permanently.Normally, less so than on a TI-Z80 or TI-68k On the one side, the Nspire has a "reformat entire memory" option in the maintenance menu, unlike the members of the TI-Z80 and TI-68k series. And even if both the boot2 and the diags were erased / invalid on a given Nspire, the serial port support of the boot1 enables transferring proper boot2 and diags, through a fairly common piece of hardware that costs $15-$20. Sure, without a valid boot1, the calculator is toast - but in commercial (production) models, the boot1 is not writable in the first place, without hardware modifications On the other side, several members of the community have TI-Z80 and/or TI-68k calculators that won't boot, and either no known software method can rescue them, or it is known that they cannot be rescued through software. Unless in-place reprogramming of the Flash chip is possible without damaging the calculator's electrical system and the Flash memory, de-soldering and re-soldering the chip is necessary... but then the chip probably won't survive the heat.
