This calculator looks similar to the TI-5040 but misses a display and outputs the results only on a thermal printer. Like the TI-5220 the TI-5015 added the useful GT (grand total) feature to the basic functions.
Dismantling
a TI-5015 manufactured in Italy reveals a clean design centered around a TMS1118
Single-Chip Microcontroller based on the famous TMS1000
core.
Similar
chips were used in the never released SR-40
(Prototype) and the successful TI-5050M.
TI-5015 A printing calculator with independent add register … and grand total. Attractive. Economical. Prints a clear, legible tape. Quickly. Whisper-quiet. © Texas Instruments, 1981 |
