An astronomical calendar that can calculate a lot of things about lights and stars. A bit like the astrolabe only that it was portable (the first laptop) this laptop is not but it is amazing the precision with which it was built and the same precision with which it is able to provide information on the stars, moonlight and stars as well as the exact time per minute .. A marvel of astronomical engineering of the 7th century .. Obviously it works only on a stationary thing and not on a ball, let alone if it turns 😂😂 Awesome!!!
