Vintage SyQuest Technology SQ555

Classic 90s 44MB 5.25" Removable Cartridge Drive • Time Capsule Find

⚠️ ITEM CONDITION NOTICE — PLEASE READ BEFORE BUYING:

• UNTESTED STATUS: This drive has been safely stored away in a sealed storage bin like a time capsule. Its functional working condition is completely unknown, and it is being sold entirely untested.
• MECHANICAL NOTE: The front cartridge door mechanism is intact but closes slowly due to old, sticky factory lubricant from the past. It will require a light clean/re-lube to restore snappy door movement.
• INTENDED BUYER: Offered strictly As-Is for parts, repair, or restoration to vintage computer enthusiasts or collectors looking to satisfy some 90s tech curiosity.

Up for sale is a physically well-preserved SyQuest SQ555 44 Megabyte internal removable cartridge drive. Before the zip drive took over the mid-90s, the SyQuest 5.25" ecosystem was the absolute gold standard for high-capacity desktop publishing, data backup, and audio engineering storage.

• Excellent Aesthetic Shape: Clean metal casing and an unyellowed front bezel make this a beautiful cosmetic candidate for a period-correct 386, 486, or vintage Macintosh restoration project.
• Internal Interface: Features the legacy standard internal 50-pin host interface and a standard 4-pin Molex power configuration connection.
• Untouched PCB: The underside logic board components look pristine and undisturbed with all factory labels remaining intact.
