 The Oric-1 was the first computer that Oric & Tangerine software released. The machine was not successful as expected, but in France it sold very well. The main problem was that when the machine was released competition was already high, bad design and a buggy ROM. Disk Drives were released in 3 inch format which helped to kill the machine even more. A Printer and a modem were released from Oric. Primary the machine was released with the idea to connect with Prestel, but the modem was very expensive. Currently a group of people formed a group and they are releasing software to revive the Oric-1.
