relation between a SR-40 and the TI-55
could easily be found with the Business Analyst
and The MBA. Both the TI-55 and The MBA use a 12-digit LED-stick and a
single-chip design and the mechanical ON/OFF slider.
The MBA gave you advanced financial and statistical functions and targeted the market above the Business Analyst. The brown housing gave the calculator a very exclusive note.
Simply by comparing the designation of the integrated circuits of the upper line "Majestic" calculators, you'll get the all members of this family:
• TMC1502 The MBA
• TMC1503 TI-55
In Europe the calculator was sold under a different name, the TI-42 MBA. Don't miss a rare Money Manager manufactured in Brazil sporting a similiar brown housing.
Powerful business calculator with statistical and financial functions…and programmability.
Pre-programmed functions computer net present value and internal rate of return for variable cash flows. Payment, present value, future value, number of periodic interest rate for ordinary annuities and annuities due. Bond yields and much more.
