Applications
The Zenith ZDS 234-890 and 234-859 are proprietary power supplies designed for Zenith Data Systems 286-class desktop computers from the mid-to-late 1980s. Zenith used a non-standard EIA-343 form factor and connector arrangement, meaning standard AT power supplies are not compatible. These units are primarily sought for vintage computer restoration, repair of legacy Zenith 286 desktops, and parts sourcing by collectors and IT technicians maintaining older Zenith ZDS equipment.
