This
TI-57 manufactured in Italy looks different to the original TI-57.
Instead of the usually molded TI-logo and TEXAS
INSTRUMENTS nameplate this one uses
just a sticker.
We know this type of display frame from some other European
calculators:
• TI-30 1st design • TI-45 1st design • Privileg SR-35NC |
Don't miss the Radio Shack EC-4000 with a slightly different sticker between the display and keyboard.
Later during production of the TI-57 the sticker was replaced to match the US-design, view a TI-57 manufactured in Italy in 1980 here.
Find a nice collection of program listings for the TI-57 on Laurent's website.
