| The **Victor 9000** was an 8088 machine released in 1981. The machine could run both MS-DOS as well as CPM/86. While using MS-DOS and an 8088 chip, it was not IBM compatible. The Victor utilized a unique floppy drive controller, its own interrupt table, and memory layout. The **Victor 9000** could utilize up to 896KB RAM, and shipped in a floppy drive configuration with two floppies or a hard-drive configuration that only had a single floppy drive. | The **Victor 9000** was an 8088 machine released in 1981.

| Applied Computer Techniques sold the **Victor 9000** in Europe as the **ACT Sirius 1**. The Sirius 1 was the same machine simply rebranded for the European market. Because IBM had difficulty meeting the supply needs of the American market, the IBM-PC was not available in Europe for the initial few years of its release. Without IBM as a serious competitor the ACT Sirius 1 was the top selling computer in Europe during the early years of the computing revolution. | Applied Computer Techniques sold the **Victor 9000** in Europe as the **ACT Sirius 1**.

| - | [todo] | + | The Victor 9000 stores data in an usual manner. The disks have a variable number of sectors per track, utilize a constant linear velocity, and spin at different speeds in various zones on the disk. The disks encode data using a Group Coded Recording |

| + | * The documentation for the Victor lists Zone 4 as ending with Track 48 on side 1 and track 40 on side two. This is incorrect. The above table reflects disks analyzed from various machines and matches the assembly code in the floppy driver. Various written documents contain this documentation bug. | ||
