AMDEK WAS A COMPUTER PERIPHERAL AND SYSTEM MANUFACTURER WHO WENT DEFUNCT IN 1986.
SOMETIME IN 2024, I WISHED TO PURCHASE AN AMBER MONOCHROME COMPUTER MONITOR AND FOUND A GOOD PRICED
ONE ON FACEBOOK MARKETPLACE. AT THE SELLER'S HOUSE, I WAS TOLD HE ALREADY SOLD THE MODEL I WAS
LOOKING AT ONLINE, BUT HE HAD A DIFFERENT ONE AVAILABLE: THE AMDEK V220A. IT CAME WITH THE
SLIGHT ISSUE OF "FLICKERING" WHERE THE SCREEN'S BRIGHTNESS WOULD NOT BE CONSTANT, INTEAD
IT WOULD BECOME EVER SO SLIGHTLY MORE FAINT BEFORE RETURNING TO ITS ORIGINAL BRIGHTNESS.
THIS PROBLEM WORSENED OVER TIME, WHICH INCREASED MY DESIRE TO FIX IT. I HAVE SINCE STARTED
WORKING WITH PEOPLE MORE FAMILIAR WITH CRTS ON THE VCFED FORUM.
TO MY KNOWLEDGE, AS OF 24/04/2026, THIS MONITOR IS ONE OF A KIND AND SEEMINGLY NO-ONE
ELSE HAS ONE, NOR ARE THERE ANY DOCUMENTS / DOCUMENTATION, ASIDES FROM MINE, AVAILABLE OF/FOR
IT ON THE INTERNET. THIS WEBSITE'S THEME WAS INSPIRED BY THE MONITOR'S LOOK.
