The label of the Educator TI-73 Explorer calculator. |
The internal
construction of the Educator TI-73 Explorer makes use of two connected printed circuit boards (PCB) for the dot-matrix display resp. the keyboard assembly. |
The PCB connected to the
dot-matrix display makes use of just one display
driver mounted on a small, flexible PCB. |
The close-up image of the
display driver reveals its genes: A Toshiba T6K04
single-chip driver for dot matrix displays with up to 128 columns and 64 rows mounted on a tape carrier package. |
The PCB connected to the keyboard sports just an ASIC (Application Specific Integrated Circuit) and the Flash-ROM. |
