A l'arrière de l'ORIC il y a POWER connexion au secteur via un adaptateur 9V, EXPANSION un port d'extension, PRINTER une sortie pour imprimante, TAPE une entrée sortie pour cassette à deux vitesses 300bps et 2400bps(prise DIN 7 broches), RGB une sortie péritel (prise DIN 5 broches) et UHF une sortie U.H.F. (Ultra High Frequency en anglais). En dessous de l'ORIC, il y a un haut parleur intégré et un bouton RESET caché dans un trou rectangulaire. Le RESET permet de reprendre les commandes sans perdre le programme. Historique : En février 1984 l'ORIC Atmos a succédé à l'ORIC 1. Il connu un succès en Angleterre (pays d'origine) et en France. Le juin 1985 ORIC fut racheté par la société française Eurêka et l'Atmos connu quelques améliorations au niveau de l'alimentation. La production s'arrêta en 1986, et l'Atmos est remplacé par le Telestrat qui est un Atmos doté d'un modem V23 permettant de créer à partir d'un simple prise téléphonique un serveur Minitel RTC. Vers 1986 des fonctions comparables sortent sur Thomson TO9+ et Exelvision Exeltel dotés d'un modem pour créer un serveur Minitel mono voie via le réseau téléphonique commuté (RTC).

Seules différences, la ROM est passé en 1.1 et des puces mémoires sont de plus grande capacité. Techniquement, l'Atmos est équipé d'un processeur 8Bits 6502A à 2 MHz mais celui-ci ne fonctionnent qu'à moitié de cycle (soit 1 Mhz) afin d'être synchro avec le processeur graphique "ULA". L'Universal Logic Array (ULA) est capable de généré deux modes d'affichage : Teletext 40x28x8 et graphique 240x200x8 pixels; il était possible de passé de l'un à l'autre. Les 16 Ko de Rom corrigé de l'Oric-1, contenait le BASIC 1.1 Tangerine (écrit par Microsoft). L'Atmos dispose de 64 Ko de RAM, mais dont 16ko sont attribué à la ROM, d'où l'appellation "48K". Le chips Audio est un AY-3-8912 Mono 7 octaves, avec 4 canaux (3 voix + 1 White noise) et 16 niveaux de volume. Le son est dirigé uniquement vers le haut parleur interne situé sous la machine.

  • Microsoft BASIC Easter Egg
    Microsoft BASIC Easter Egg Commodore PET Microsoft 6502 BASIC has its roots in the Commodore PET Commodore bought MOS in October 1976 and worked on converting the KIM platform into a complete computer system. They licensed Microsoft BASIC for 6502 (also October 1976), renamed it to Commodore BASIC, replaced the “OK” prompt with “READY.”, stripped out the copyright string and shipped it in the ROMs of the first Commodore PET in 1977. In 1979, Commodore started shipping update ROMs with a version 2 of Commodore BASIC for existing PETs. Apart from updates in array handling, it also contained what became known as the WAIT 6502 Easter egg. If you type “WAIT6502,1” into a Commodore PET with BASIC V2 (1979), it will show the string “MICROSOFT!” at the top left corner of the screen. The Easter egg code does not print the characters through library routines, but instead writes the values directly into screen RAM. While BASIC used the ASCII character encoding, the Commodore character set had its own encoding, with “A” starting at $01, but leaving digits and special characters at the same positions as in ASCII. Thus, when the 10 hidden and obfuscated bytes a1 54 46 8f 13 8f 52 43 89 cd has their two most significant bytes stripped becoming 21 14 06 0f 13 0f 12 03 09 0d and then reversed, on the PET they decode into: MICROSOFT! Although this particular version of the Easter egg was written for the Commodore PET, Microsoft did not encode its company name in BASIC specifically for Commodore: The 9 digit BASIC 6502 version 1.1 for the KIM-1 contained the 10 hidden bytes: The version of Microsoft BASIC for the 6502-based Apple II, called “AppleSoft“, contains the same 10 bytes KIM-1 BASIC was released in 1977, AppleSoft II in spring 1978, and the V2 ROM of the PET in spring 1979.

The Oric ’ s quite nice if you like a 6502 machine, but there ’ s loads more games for the Spectrum… You don ’ t like the rubber keyboard?

We use the term to refer to an altogether different object on our side of the Atlantic. In the U.S.A., an Apple II is a home computer; the IBM PC in its smaller configurations is a home computer; the Macintosh is a home computer. In the U.K., those computers would be considered rather expensive as business computers, let alone for home use.” Dick Pountain, BYTE Volume 10 Number 01, 1985, p.401 4 Notable Exceptions: The Newbear Electronics 77/68 1977, £50 (~£314) ● CPU: Motorola 6800 ● RAM: 256 bytes ● Arguably the first British home computer ● Exclusively sold as a kit ● Direct-memory toggle switches 5 Notable Exceptions: The Nasco Nascom 1 1977, £229.19 (~£1,397) ● CPU: Zilog Z80 ● RAM: 2 kilobytes (to 32KB) ● Launched as a kit, later available preassembled ● Included full-size keyboard and video output ● Sold as “evaluation kit”
