The
TI-5045 SV (SuperViewTM) replaced
the short living TI-5045 IIA and could be called a
TI-5034 SV with two color printing.
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.
The
later one, manufactured early in 1996 uses the TC-83220-0027 circuit.
We could assume that Toshiba simply renamed the old chip.
The UL-File number
E122921 is unfortunately not active, we can't reveal the manufacturer of the
calculator. Don't miss the database
of all known UL-File numbers found on Texas Instruments calculators.
Just
to be complete, the elder TI-5045 SV was manufactured for the German market and
bears the GS-Logo instead the UL-Logo.
