Sirius I
The Victor 9000 / Sirius 1 was a personal computer that was developed by the American engineer Chuck Peddle . He had already developed the Commodore PET 2001 before . The computer appeared in the same period (1981/82) when the first IBM PC came onto the market. However, the Sirius 1 was far more innovative and better than its IBM counterpart in some points. The computer was equipped with a Intel - 8088 equipped processor (4.77 MHz). The memory of the device consisted of 128 KByte in the basic version, but could be expanded to 1 MByte. The high-resolution graphics of the Sirius could only be fully used from 256 KByte. The Sirius 1 had two RS-232 interfaces and could be operated with the CP / M-86 and MS-DOS operating systems.
In Europe, the Sirius 1 was even relatively successful, as this computer appeared there before the IBM PC. The computer could not establish itself worldwide and was quickly overtaken by the IBM PC in terms of sales.
Technical features
The computer had a 12- inch monochrome monitor that had an anti-reflective coating. The contrast and brightness of the monitor could be controlled directly from the keyboard. Even then, the computer was able to display the very advanced resolution of 800 × 400 pixels.
The Sirius was supplied with an internal sampler , with which one could record short sound sequences and then play them back. A light pen could also be connected to the Sirius 1 .
The Sirius 1 was offered in three hardware configurations:
- 2 5¼ ″ floppy disk drives of 600 kB each. 128 kB RAM
- 2 5¼ ″ floppy disk drives of 1.2 MB each. 128 kB RAM
- 1 5¼ "floppy disk drive of 1.2 MB each. 10 MB hard disk. 256 kB RAM.
