Hyundai HMM-1200 12" Monochrome Amber CRT Monitor 9-Pin TTL No Base 1989
The Hyundai HMM-1200 is a 12-inch amber phosphor monochrome CRT monitor designed for IBM PC-compatible computers using a 9-pin TTL video interface. Manufactured in December 1989 by Hyundai Electronics Industries Co., Ltd. in South Korea, it is a representative example of the desktop monochrome displays that were standard equipment for DOS-era personal computing. The amber phosphor screen produces a warm orange-on-black image commonly preferred over green phosphor for extended text work.

Applications
Amber monochrome CRT monitors like the HMM-1200 were the standard display for IBM PC, PC/XT, and PC/AT systems running DOS-based software through the late 1980s and into the early 1990s. They accept TTL-level video signals from MDA (Monochrome Display Adapter), Hercules Graphics Card, and CGA cards operating in monochrome TTL output mode — all common in that era's IBM-compatible hardware. Amber phosphor was widely regarded as easier on the eyes than green for long sessions of word processing, spreadsheet work, and database entry, making it a popular choice in office and business settings. Today these monitors are sought by vintage computer collectors and enthusiasts restoring period-correct IBM PC, XT, and AT systems, as well as by operators of legacy industrial, point-of-sale, or scientific systems that still rely on DOS-era hardware with TTL monochrome video output.
This Hyundai HMM-1200 12" Amber Monochrome CRT Monitor has been inspected and appears to be in good used condition. The housing shows minor surface marks on the bezel, visible in the close-up photos, but no cracks or significant damage. The green power LED is present on the front panel. The monitor was pulled from a working environment where it was previously in use. Please note: the tilt/swivel base is not included — the monitor head only ships. Please view our photo set and contact us if you have any questions.
