Applications

The CM1474AMA was produced in the late 1980s as a combined color monitor and television display, a form factor that was common in that era for workstations requiring a single display to serve both computing and broadcast/video monitoring tasks. The 9-pin analog DB-9 interface was a standard connection used by a range of computers and video cards of the period, particularly in IBM PC-compatible and proprietary workstation environments. The 48.4 kHz horizontal sync rate places this display in the medium-resolution class for its era — above standard NTSC/CGA but consistent with EGA and early VGA compatibility ranges. Matrox Electronic Systems, a Canadian company best known today for professional multi-display graphics cards, was in the 1980s also producing display hardware and peripherals for both commercial computing and military/government use, as evidenced by the NSN (National Stock Number) on this unit. Displays of this type are still sought after by collectors of vintage computing hardware and for use with period-correct computer systems that output analog DB-9 video signals.
