A nice TI-30 suitcase used in schools. It can charge 20 calculators at the same time. Thanks to @hellomoles for the donation.
The calculators were all built in the RCI factory in Rieti (1982/1983).
If you have the opportunity to support those who work for free, in this non-profit museum, and with the aim of opening a museum in the city of Rieti dedicated to Texas Instruments. DONATE !
