Altos Model 5-15ED

The 1981 Altos Model 5-15ED was an  8 bit microprocessor based system with dual floppy and Winchester hard disk together with single board microcomputer technology.

The Altos Series 5 computer system was a Z80A-based multiuser system designed to fit many commercial, technical, industrial, Scientific, and educational applications. It ran under either CP/M, MP/M II, or OASIS operating systems. In its basic figuration, the system was contained in a single chassis, however additional chassis could be connected to the basic chassis to increase system capabilities*

The basic computer system includes the CPU, four RS-232-C ports, one parallel port, 192 kilobytes of RAM, all peripheral Controllers, and one 5-1/4 inch floppy disk drive. You have to add a keyboard  terminal, provide your own floppy diskettes and cabling. 

Series  5-5D also included a five-megabyte drive and a five-inch hard disk drive.Series 5-15D also  included a  second one-megabyte disk drive unit.

Our Altos is a model 5-15ED with a serial number of 50-12302. This unit which is in excellent condition was very kindly donated by Trevor Scott together with
