that texas instruments and ibm might be worth more on
ebay. I've scrapped hundreds of older computers and don't recall seeing any of those
To the OP, with a philips screwdriver and 5 or 10 minutes you should be able to scrap about any computer ever built. They have almost always been constructed with replaceable parts in might ( hence the IBM compatable, all companies parts fit the same way ) They can be creative sometimes in getting them to all fit. The orneriest ones I know of were the early HP, sometimes you couldn't figure out if the shell slid off from the front or from the back, and as you're laying your 2 prybars down and scratching your head and realize it slides off easier the OTHEr way
But most computers come very easily in pieces usually with just a very few philips screws
