Zeiss Humphrey Matrix FDT Visual Field Analyzer 715 Parts only or repair

Description

This Zeiss Matrix 715 was used until a few years ago, when it wouldn't boot consistently. I put it in the closet, planning to have it repaired. That was before Covid. We have since closed a location and I don't need this anymore.
Includes the main unit as pictured. Does not include the keyboard, does not include the clicker, does not include any manual or documentation. I do have access to the printer, but am not including it in this sale to save on shipping expense. If you want the printer I can create a buy it now ebay listing for it.
I believe the problem is the hard drive, but could be something else. When attempting to turn it on it would start the bios screen and then freeze within minutes. Sometimes it would boot to be operational, but it took several attempts.
This unit should be purchased only by someone who needs parts, or knows how to fix it. Please don't buy it expecting to have a working visual field machine.
Unit will be packed carefully, so it arrives in the same condition it currently is. Please ebay message me with any questions.
