My problem: I have a Texas Instruments TI-58C (made in Brazil). I bought this calculator new in Brazil on April 22, 1981. It has been stored without batteries for 20 years or more. Recently I took it out to use it. My calculator is displaying strange memory and program storage behavior. Sometimes it works as expected, but most of the time it does not store the correct number. For example, if I store the number 99.99 in a memory, it returns something like 9999000090. Do you think you may have a damaged memory IC? My calculator has a NEC D445LC memory IC, as opposed to the common ToshibaTC5047AP-1. I think in replacing the D445LC for a ToshibaTC5047AP-1 IC. What do you think about? Or may another problem? Thanks, Danton Brazil. |
