The
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:
 | TMC1501 TI-57 |
| TMC1502 MBA |
| TMC1503 TI-55 |
In Europe the calculator was sold under a different name, the TI-42 MBA.
