Alpha Microsystems (Santa Ana, CA)

The AM100 was an early 16-bit microcomputer with a CPU based on the design of, but not compatible with, the DEC LSI-11. It was highly expandable and could be used in multiuser environments with enough memory and disk storage. The company is still in business, and it proudly claims the AM100 as the world’s first multiuser, multitasking microcomputer.

The AM-500 series worked as standalone PCs or as terminals on a multiuser network. Units with a 10MB hard disk drive were labeled the AM-510.

The AM-1000 series was primarily a line of multiuser systems based on the 68000 CPU and Alpha Micro’s AMOS operating system. CP/M was also available as an option.
