The Oric Atmos was released in 1984 by Tangerine Computer Systems as a successor to the Oric-1. It featured a 1 MHz 6502A CPU, 48KB RAM, and an improved keyboard. It was particularly popular in France and the UK.
This emulator faithfully recreates the hardware including the 6502A CPU, HCS 10017 ULA video chip, AY-3-8912 sound chip, and MOS 6522 VIA chip.
