Well my TI 84+SE decided that it had enough and self destructed. Most of the calculator is fine but the microprocessor got fried. Instead of buying a new calc what microprocessors would you recommended I use to replace the dead one?
thank you for helping |

| It's actually 6MHz or 15MHz, depending on which speed is set. |

It'd be a shame to have to use a 68k when all you carry is a z80, or vice versa.
[EDIT]
Whoops, I misread.

I believe that the 84+SE uses an ASIC. That is to say that several of the components are bundled into a single, TI-84+ specific chip containing the Z80 MPU, RAM and (I think?) the USB controller. In short, the only way to replace it would be to pinch one from another TI-84+.
This is in contrast to the 83+, which uses discrete, original ICs.

Quite, the 84+es have an ASIC, rather than the discrete components in the 83+es.
Benryves is totally right, as usual.  |
