Oric Atmos

Historia

In late 1983 the funding cost for continued development of Oric caused external funding to be sort, eventually lead to a sale to Edenspring Investments PLC. The Edenspring money enabled Oric International to release the Oric Atmos, which added a true keyboard and an updated V1.1 ROM to the Oric-1. The faulty tape error checking routine was still there. Soon after the Atmos was released, the modem, printer and 3.5-inch floppy disk drive originally promised for the Oric-1 were announced and released by the end of 1984. A short time after the release of the Atmos machine, a modification for the Oric-1 was issued and advertised in magazines and bulletin boards. This modification enabled the Oric-1 user to add a second ROM (containing the Oric Atmos system) to a spare ROM-socket on the Oric-1 circuit board. Then, using a basic DPST (double pole single throw) switch, the users could then switch between the new Oric Atmos ROM and the original Oric-1 ROM.
