Teardown: Texas Instruments Extensa Laptop

July 19, 2012

After shorter period of vacation I have returned back home. Straight of I will start with posting a teardown of “ancient” laptop made by Texas Instruments. This beast is powered by x486 100MHz processor and whooping 8MB of RAM 🙂

Biggest surprise to me was rechargeble battery from Duracell, just wait and you will see on photos what I am talking about.

Let’s start with actual teardown:

Battery I was talking about. Specs are 10.5V NiMh, but Ah it is not specified. Sadly battery is dead so I cannot measure it or use it.

Image

Diskette reader/writter for 3.5″ diskettes.

Image

Image

Hard disk which is close to if not exactly the same size as modern disks with plates inside. 540MB had to be enormous in time when this laptop was released, but today sadly it cannot satisfy needs of individual.

Image

Detatched keyboard from laptop, it is pretty slim in my opinion.

Image

Image

First sight of what is under keyboard. You can see small metal heatsink for processor. Under that is some sort of thick copper tape, I have no clue what was that used to protect.

Taking motherboard out you are left with plastic shell and monitor.

Image

Closer look of what was hiding under the metal heat sink. You can spot 100MHz processor on which is also Windows compatible logo 🙂

Some manual soldiering of jump wires afterwards when motherboard was allready assembled, guess the forgot something or found better solution for problem they faced.

Image

Memory slot and memory itself. Wonder what could we used 8MB of memory today:D Probably you couldn’t watch this blog in high def pictures 🙂
