I checked if the system could boot with the power supply units from the other 98 units. It seems the system can boot, but many parts are missing, such as screws for various components and the case, two 5-inch FDDs, and the power supply unit. Please consider supplementing these from other sources or using this unit for parts. *The display, power supply unit, and related items are for testing purposes and are not included. Please understand that this item is a junk item for repair or parts and purchase accordingly.
