Collector's Item
The Jangbu Ilsaek 1990 is now considered a rare and collectible item among retro gaming enthusiasts. If you're interested in purchasing one, be prepared to pay a premium price, as units in good condition are hard to find.
Ask any collector why they obsess over the Jangbu Ilsaek 1990 Portable, and they will point to the screen. The "Ilsaek" amber display is legendary not just for its color, but for its afterimage quality. Due to a unique capacitor leakage issue (now affectionately called "the Jangbu rot"), when you turn off the machine, the last image burned into the screen can remain visible—faintly—for up to three days.

There is an urban legend in Korean tech circles: A finance professor at Yonsei University used a Jangbu Ilsaek in 1991 to type his resignation letter. He turned off the computer, left it in the department closet, and emigrated to Canada. Five years later, a janitor plugged the machine in, and the word "Sagan" (사직 - resignation) was still faintly glowing on the amber screen. Whether true or not, the story cemented the machine’s reputation as the "Ghost of Korean DOS."
The machine booted from a floppy disk into a custom DOS-compatible OS called “Red Star 1.0” (붉은별 1.0) – not to be confused with the later Linux-based Red Star OS. This was a heavily modified MS-DOS 3.31 clone with:
All software was distributed on floppy disks with a holographic Kim Il-sung seal to prevent unauthorized copying—though the security was easily bypassed with a standard sector editor.
In 1990, the South Korean computer market was undergoing a transition. The "8-bit" era (dominated by MSX computers like the Goldstar FC-200 and Samsung SPC-800) was giving way to the 16-bit era (IBM PC compatibles running MS-DOS).
During this period, software localization was a major challenge. Most business software was imported and in English, creating a high barrier to entry for Korean small-to-medium business owners. Jangbu Ilsaek emerged as a solution, offering a fully Korean-language interface tailored to local tax laws and accounting customs. Which would you like
Here is the core mystery: No physical unit has ever been photographed outside of a single, grainy press photo from a 1989 trade show.
In November 1989, at the Korea Electronics Show (KES) in COEX, Seoul, Jangbu reserved a small booth. According to a single surviving clipping from the Busan Ilbo newspaper (December 2, 1989), Jangbu displayed a wooden mockup labeled "Ilsaek 1990 Portable." The article notes that the product was "coming in Q2 1990" and featured a revolutionary "snap-on" expansion bay.
There are three prevailing theories for the device's disappearance:
The most tragic theory. In April 1990, a delivery truck carrying the first 500 production units of the Jangbu Ilsaek was involved in an accident near the Han River. The truck's rear door opened, and the pallets of computers fell into a concrete construction site, where they were quickly buried and poured over. Unable to afford a second production run, Jangbu folded. To this day, construction crews near the Yongsan district occasionally joke about digging up "Jangbu gold."
The Ilsaek 1990 Portable was never sold commercially outside the DPRK. It was issued to:
By 1995, most units were recalled due to a widespread capacitor plague (likely cheap Soviet-era components). Today, fewer than twenty units are believed to exist outside North Korea. Collectors in South Korea, Japan, and Germany have paid upwards of $8,000 for non-working specimens.
Jangbu Ilsaek (Korean: 장부일색) is a historically significant piece of software in the history of South Korean computing. Released in the late 1980s and widely used through the early 1990s, it was one of the first mass-market accounting packages designed to bring financial management to the nascent personal computer market in Korea.
