TI-5045SV_PCB2.jpg (101225 Byte)Dismantling two TI-5034 SV reveals a surprise, they use different printed circuit boards (PCB's). The elder calculator, manufactured already in July, 1993 makes use of a Toshiba T7872-0016 single-chip calculator circuit.

We could assume that Toshiba simply renamed the old chip.
