This TI-1040 was sold together with some unknown accessories as "TI-1040A Tax Pak" and looks at first glance like a standard TI-1001. Comparing these two calculators reveals an astonishing difference: These calculators make use of two different display frames:
Rectangular design: TI-1001,
• Rounded design: TI-1010, TI-1030, TI-1040, TI-1070 calculators.
Collectors, I need your help. If you know the accessories delivered with the TI-1040A Tax Pak, please contact me: firstname.lastname@example.org
This particular calculator was manufactured in December 1980 and makes still use of the printed circuit board (PCB) and single-chip calculator circuit TP0311 introduced in 1978 with the TI-1030.
