Googling around has led me to http://120293-0001revkmicrosemiconductor.blogspot.com/, which greatly puzzles me.

Guessing it's an affiliate marketing scheme. Some guy made a bot that generates blogspot blogs that refer to various Amazon products. When you click on any of those Amazon links they'll use his affiliate id.

Actually it's not an affiliate bot. Whatever a microsemiconductor is, it costs 10 million dollars:

I also enjoy the negative 9 million dollar discount you get.

Does anyone know what a microsemiconductor does?

Amazon affiliate advertising bot.

I have added it to my Amazon Whish List ...

They make up for it with the $10 shipping.
