As usual within the Majestic line you'll find both calculators with and without chrome-border around the display. Compare this calculator with the original Business Analyst-I.
The Business-Analyst-I and all other (except the SR-51-II and TI-45) calculators in the Majestic-line used a LED-stick carrying the whole electronics! The printed circuit board (PCB) of this late Business Analyst-I is identical with the original SR-40 but uses a TMC0982 calculator circuit instead the TMC0981.
