Good points

Excellent keyboard
Built-in printer port

Bad points

Cassette loading was better than on the Oric 1 but still not fully reliable, especially with the original V1.1 ROM..
No longer had a clear price advantage over its rivals.

How successful?

Not as popular as it could have been, though like the Oric 1 the Atmos sold quite well in France, probably around 100,000 units.
The Atmos was launched as the home computer market was saturating and lacked the large software base of established competitors like the Sinclair Spectrum and Commodore 64.

Comments

A matching four colour pen plotter and 3 inch disc drive were available.
The Oric Atmos was essentially the Oric 1 with a better keyboard and most of the bugs removed.
Theoretically the Atmos was superior to its arch rival the Spectrum and had the Atmos been launched at the beginning of 1983, rather than the flawed Oric 1, it could have been one of the topselling micros.
As it was it arrived too late to make a real impression.
