This was yet another model number from the Majestic Line that was exclusive to Europe. You can just barely see "Assembled in Italy". It was introduced in 1977, though my unit appears to have a date from the second half of 1978.
The internals are the same as the TI-30 or SR-40. However, the keypad covers up some buttons. I haven't opened mine, but I have been told that the contacts for the missing buttons are still there. I'm not sure why they did this. I know that some calculators were released with some functions disabled to be used for education. An example would be the ABLE line. However, I'm not sure if they did see something similar here.
My calculator has some issues with double presses happening with some keys. That could be due to the age of the membrane, or the battery may be pushing the board too far forward. Otherwise, it is in great shape. This calculator is supposedly quite rare today. To make matters worse, it can be difficult to search for on Ebay, due to the TI-15 name being reused for much more common calculators later on. I have this same problem with the TI-31, which is why I don't have one of those yet.
