The laptop was built in probably 1990, which is ancient history for most any computer. Amazing it still even works. It was a sort of a nettop before anyone ever though about nettops. As you can or will see the floppy and the dvd-rom drive were external so that you did not have to use them unless you needed to. Hard frive is removeable also.
Note: you could do this just one machine or a whole office or school.
Step 1: Doing fine
At one time the laptop ran MSWindows ME, then that was evenutally changed to linux when Microsoft stopped supporting MSWindeows ME. The laptop is running fine when I needed to use the floppy drive. Wait, there is no real software for floppy might as well get rid of it.
Step 2: There goes the DVD-rom drive
Step 3: HD is dead.
Step 4: Is that a cable?
Impossible you say?
Step 5: Overview
No computers were damaged or killed in the making of this video. In fact all the parts still work, except for the power on button cover that became apart. The removing of the parts was all done for dramatization.This instructable was a good example of IAAS (Infrastucrure as a service) Just one facet of cloud computing. Wikipedia talks about IAAS at : https://en.wikipedia.org/wiki/Infrastructure_as_a_service
What was done was not a trick, so how was it done? See: http://www.instructables.com/id/Another-almost-free-computers-thin-client-set-up/
