Matrox MACS Z80
[Vin 166]
The Matrox MACS Z80 was a notable vintage computer system built around a Z80 CPU and utilizing Multibus form factor cards. Its significance lies in integrating robust industrial-grade components like dual 8-inch floppy drives running CP/M 2.2, a Matrox ZBC-80 CPU card, and advanced Burr Brown A-to-D converters, marking it as a reliable system for data acquisition and industrial control in the early 1980s. While not a mass-market personal computer, it was important historically for its modular design and precision analog capabilities, positioning it as an OEM solution in industrial and scientific applications.

Notables
-
The Matrox MACS Z80 was one of the early industrial-grade microcomputer systems built on the Multibus standard, which allowed modular, expandable hardware—an important precursor to modern industrial control systems.
- Matrox is a Canadian technology company founded in 1976 by Lorne Trottier and Branko Matić, based in Montreal, Quebec. The company started by focusing on specialized video interface products for microprocessors, pioneering video RAM and early graphics controllers that helped establish the market for computer graphics hardware.
-
It featured high-precision analog-to-digital conversion using Burr Brown components, notable for scientific and data acquisition tasks rather than typical personal computing.
-
While not widely popular in the consumer market, it was respected for its reliability and ruggedness in OEM and industrial environments.
-
The system’s firmware, labeled “Montrax v3.00,” is a unique identifier that hints at specialized software tailored for industrial uses.
-
Unlike many Z80 systems of its time, the MACS Z80 integrated dual 8-inch floppy drives, which were relatively large and uncommon in personal computers but standard in industrial and professional settings.
-
Historically, the MACS Z80’s importance lies in bridging early microprocessor computing with precise analog measurement technology, marking it as a specialized tool rather than a mass-market computer.
