The Altos 586-10 was a powerful multi-user microcomputer released in the early 1980s by Altos Computer Systems. It was specifically designed for small businesses that needed a central system capable of supporting multiple terminals simultaneously.
1. Architecture and Processor
Unlike many home computers of the era that used 8-bit chips, the Altos 586 was built around the Intel 8086 16-bit processor, typically running at 8 MHz. This allowed the system to handle more complex tasks and manage multiple users more efficiently than its predecessors.
2. Multi-User Capabilities
The standout feature of the 586-10 was its ability to support up to 5 users (and later expandable even further). Users would connect to the main unit via ”dumb terminals” using serial RS-232 ports. This made it a cost-effective solution for offices, as they only needed one expensive central computer and several cheaper terminals.
3. Storage and Memory
The ”-10” in the model name usually referred to its storage capacity:
-
Hard Drive: It featured a built-in 10 MB hard disk, which was massive for the time.
-
Floppy Drive: A 5.25-inch floppy drive for backups and software installation.
-
RAM: It typically shipped with 512 KB of RAM, expandable up to 1 MB.
4. Operating Systems
The Altos 586 was versatile in its software support, often running:
-
Xenix: A version of UNIX developed by Microsoft, which was the preferred choice for multi-user business applications.
-
MP/M-86: A multi-user version of the CP/M operating system.
-
Pick OS: Known for its integrated database capabilities.
5. Networking and Legacy
Altos was a pioneer in local area networking. The 586 series supported Altos-Net and later Ethernet, allowing multiple Altos systems to be linked together. The 586-10 is remembered as a ”workhorse” that bridged the gap between expensive minicomputers and the emerging IBM PC market.
