This TI-30 manufactured in Italy looks different to the original TI-30. 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-45 1st design
• TI-57
• Privileg SR-35NC

Even some US-manufactured calculators got the sticker:

• Radio Shack EC-4000

Later during production the sticker was replaced to match the US-design, view a TI-30 manufactured in Italy in 1980 here.

In the meantime we discovered a rare TI-30 with a completely different keyboard technology.

Don't miss the rare TI-30/super manufactured for Koh-I-Noor Hardtmuth.
