The Oric-1 (Tangerine, 1983) and the Oric Atmos (1984) are British home computers built around a 6502A at 1 MHz, a 6522 VIA, an AY-3-8912 sound chip and a custom ULA that draws a 240×224 colour picture using serial attributes. The emulator runs the original BASIC ROMs on an emulated 6502, in real time, with sound, `.tap` tapes, the Microdisc with Sedoric, snapshots and game layouts.

**You must have a Pico 2 or equivalent to run this emulator.**
