Some modifications were made to the cassette interface, the RAM memory was increased to 64 Kb and now only one ROM chip holds the new version of the Basic interpreter. **(1)** A new FUNCT key is added to the keyboard, but is not used for anything ! You have to program it yourself.\ **(2)** 5 volts regulator with its cooler.\ **(3)** Unique 16 Kb ROM chip holding the improved version of the Microsoft (not official) Basic interpreter.\ **(4)** MOS 6502A 8 bits microprocessor.\ **(5)** AY-9512 sound chipset (3 voices, 7 octaves).\ **(6)** Eight 4164 memory chips (64000 cells x 1 bit) holding the 64 Kb. RAM memory used for user programs and text / graphic display.\ **(7)** Internal loudspeaker. Sound was one of the good features of the Oric systems, though there were no way to control the volume of this internal speaker.\ **(8)** TV signal modulator.\ **(9)** RGB video out connector (DIN) for a monochrome or colour monitor.\ **(10)** Cassette interface connector (DIN) with remote control.\ **(11)** Parallel / Centronics port (not standard) used to connect printers.\ **(12)** Expansion connector, used for example by the numerous disk-drives available for the Oric. null title subtitle text image THE BOX null title subtitle text image BOX #2 null title subtitle text image BOX #3 null title subtitle text image YOUGOSLAV NOVA64 A Yugoslavian company, Avtotehna of Ljubljana got a licence from Oric to make 5000 machines. All the parts were shipped from the UK. Some people in Yugoslavia suggest that more than 5000 were made, mostly for local schools.\ The Nova64 was same machine as the 48K Oric Atmos, apart from the power supply unit that could power both the computer and an separate 3.5" 2x400 KB FDD unit.\ A Yugoslav version of the manual was also available.

The flaw?... No, it is not that it is rather difficult to use such a serious configuration for hours sitting on the floor. The flaw comes rather from the photographer who forgot to do the housework before taking the picture and left to posterity his accessories cartons right behind the low dresser. null title subtitle text image FRENCH BROCHURE FRONT Description of the complete Atmos system.

I bought the Oric rather than a Sinclair ZX Spectrum because I liked the proper bus expansion connector on the back and I wanted to experiment. It''''s actually my second one since the cassette input failed in a few weeks on the first. The replacement failed too but by then the Oric-1 circuit diagram had been published in Oric User Magazine and comparing the diagram with what was actually in my Oric-1 (it wasn''''t quite exactly the same) I could see part of the cassette interface that looked badly designed so I tried fixing it and it worked!!! The solution, if you have an Oric that won''''t load from cassette is to fit a pull-up resistor on the input from the cassette interface to the 6522 VIA chip. I just soldered the resistor under the PCB across pins 18 and 20 of the 6522 VIA. I used 2k2 but 4k7 would probably be plenty. The original design used only the on chip pull-up but I knew from experience that the pull-ups in the 6522 were often very weak. author date text Danilo (Netherlands) Saturday 19th January 2019 Though teh computers both didn$t sell in great numbers, the really addicted fan''s bought a very versatile home computer with an excettekt manuak which included a full course in Basic and an full explanation on alle the commands the Oriac an Atmos worked with. But there was al lot of competition at the time. author date text Glyn Harper (Isle of Man) Saturday 7th April 2018 The Atmos was the first computer I ever owned! I saved up half the money, and my parents paid the other half.\ All my friends had either commodore 64’s or Spectrums, but I wanted something more serious. I think basically I fell in love with the black and red keyboard design! Aesthetically it was the nicest machine around.\ Sadly it died after a few months and Oric had gone, so Dixon’s swapped it for the nearest thing, a Spectrum plus.\ About 20 years ago I was in touch with someone who worked at Oric, and managed to get a brand new machine as they’d kept a few when they’d gone bust. So now I once again have a working Atmos, that sits pride of place in my collection. author date text Rob Davis (Telford, Shropshire) Monday 29th February 2016 I took the dear old Oric Atmos from the attic in July 2015 and it all worked perfectly, the disc drive still functioned and all the discs had their data intact after 30 years. Amazing! author date text Jules (Poole Dorset / UK) Tuesday 13rd November 2012 I had an Atmos.\ I agree with the quality of the manual. A tutorial on 6502 MC code programming and a list of the rom function calls. That taught me real programming when I was 14.\ I also found that I needed a serial port and built my own on vero, from a design in a magazine. Then wrote a simple mc code dumb terminal emulator program, with my new found skills.\ I did buy one of the floppy drives, but had lots trouble getting it working. Eventually it was discovered that I had been shipped a slave drive, rather than a master. But by the time we had worked this out, Oric had gone bust. (Though the new owners did help me out and got me a proper master drive. Thanks lads.)\ It''s still all in the loft. Will have to drag it all out and see if it works. That will be a shock for the kids!! author date text Rob Davis (Telford, Shropshire) Friday 11th March 2011 I learned all about programming on the Atmos, which I still have and with its disk drive, still works, the data intact from over 25 years ago. The user manual was quite outstandingly good, the best computer manual I have ever seen. When I started out in home computing I was advised that "If you''re a user, buy a Spectrum, if you''re a programmer, buy the Oric." It was fantastically accurate advice. I''ve now a Master''s in IT and work developing multiuser corporate databases - all thanks to skills learned on the Atmos. author date text baba bont (Holland) Friday 21st January 2011 I''ve made my final paper on an Oric Atmos using Author.\ Great small keyboard with all the necessary keys.\ Together with an Brother HR-5 (Thermal paper $-) it was a combination to beat!\ Better than the IBM word processor machine of IBM at the hotel I worked. A pity, marketing was not the best of this Oric author date text Philip Ayres (UK$) Sunday 5th September 2010 $quote$\ Apparently the BBC used the Atmos to provide the video displays in the space hopper spaceship for the final season of Blakes7.......not sure if thats true...!\ $/quote$ Well seeing as Season 4 of Blake''s 7 aired the tail end of ''81 and the ATMOS was released early 84..... NO! author date text Rosdi (Seremban, Malaysia) Tuesday 24th June 2008 I upgraded to the Atmos from the ORIC-1 (I was a student nurse at Ealing Hospital, London). I feel it was way above several other microcomputers at that time. As I understand it Oric International made a wrong marketing strategy. Otherwise things could have been different, especially with the Stratos waiting in the wings. My programming skills were honed on the Oric 1 and Atmos. It was fun working on it, even when translating Sinclair BASIC and BBC BASIC into Oric BASIC. Sometimes I still miss the Atmos. author date text Christian (Cumbria, UK) Wednesday 4th April 2007 Apparently the BBC used the Atmos to provide the video displays in the space hopper spaceship for the final season of Blakes7.......not sure if thats true...! author date text Panagiotis (Athens/Greece) Tuesday 7th December 2004 That’s my first and unforgettable computer at 1984 (13 years old I was). Currently, I am a computer scientist but I can't describe my feelings when I touch the black keys of the black-red case with the upper-right logo "Oric Atmos 48k" on it. This computer offered excellent programming environment (for its money and that period of time) especially for amateurs with a powerful basic and excellent sound and graphics capabilities. BUT in addition to all the above, the overall design of the computer, the production history that has and the passion of ORIC users, is the reason that I consider ORIC a LEGEND in computer history. author date text Arakeen (France) Thursday 16th January 2003 When it was quite hot (it was rather fast...), it was enough to press the plastic with two hands so that it is blocked... ( sometimes even without the hands...)\ Ah là là, that it idescriptible emotion to see all his work lost after 10 pages of Hébdogiciel... I cry about it still today... author date text George (Athens/Greece) Saturday 20th April 2002 Very nice home micro. It's a pitty that it did not overcome the Sinclair Spectrum. Things could be different in the mid '80s. /museum/oric-1 /museum/oric-nova-64 /software/aigle-d-or-l /software/manoir-du-docteur-genius-le /software/moria-also-known-as-the-mines-of-moria /software/retour-du-docteur-genius-le /software/xenon-1 /software/zorgons-revenge 79 url date https://web.archive.org/web/20230609053334/http://www.old-computers.com/museum/computer.asp?c=79 2023-06-09

The Oric Atmos was the successor of the Oric 1 and had almost the same features. Its main difference with the Oric 1 was the keyboard and the debugged ROM (the ORIC 1 had several bugs). Although improved, the loading process from tape was still very uncertain. The real mechanical keyboard was really better.

Two versions were available, with 16 or 48 KB of RAM. 16 KB version couldn't be upgraded, very few of them were sold.

There were also new Basic instructions and above all the Scart power supply was integrated on French models from 85! Fantastic, when you know that the Oric had the world record of cables and power supplies you had to use (1 for the computer, 1 for the tape recorder, 1 for the peritel supply and 1 more plug for the TV!).

The Atmos had really large success in France like its little brother the Oric-1. A lot of videogame companies got off the ground thanks to this machine, and quite a lot of people have a tender thought when then remember their Atmos.

In 1985, Eureka Informatique, a french company, bought back Oric. The Atmos then lived a bit longer thanks to some improvements (peritel power supply and better tape reliability) and cheap prices policy.

The Atmos was somehow legally licenced in Yugoslavia as the Nova 64.
The Pravetz 8D was a bulgarian clone of the Atmos.
