Changes

Dr. Jones showed me how to remove computers from their rack, starting with Geo 4 I think. But I probably started work on Geo 2 instead of Geo 4. He wanted me to remove and discard the motherboards of those computers but keep the memory. I started disconnecting cables from the motherboard and unscrewing it from the case, but I was not sure what to do about the PATA ribbon cables. In the computer in 405, I had tried to disconnect the ribbon cable from the motherboard, but it was too firmly attached to come loose. I thought it might not be meant to come off because it was an essential part of the motherboard. Maybe removing it would damage the cable or the motherboard. Then Brendan came and showed me what to do. He disconnected the ribbon cables and removed a bracket above the motherboard that would prevent it from coming out. After that, I knew how to remove the motherboard. I tried to remove one of the processor fans and its heat sink, but when they would not come off I decided to leave them on the motherboard and throw it away.

I vacuumed Geo 4 outside and inside before removing the motherboard. I had also vacuumed Geo 2. When vacuuming, I kept my hand on the grounding mat to avoid any destructive electrostatic discharge.

I took the motherboard out of nod 22.
