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.

Release v1.1

What’s new

  • Exit to shell. A new item on the menu’s main page, between Save settings and About, returns to the PicoCalc shell when the emulator was started from it under UF2 Loader. The running program is lost, as by a power-on. It refuses, and says why, while a tape recording is not yet on the card, when the emulator was not started by UF2 Loader, or with no card to load the shell from.
  • File times from the shell. Files the emulator writes to the card (settings, tapes, discs, snapshots, screenshots) are stamped with the shell’s date and time, in its local time. Started without the shell, they keep the fixed date of 2026-01-01.
