Teensy 3.0 compared to Tandem Non stop 2

Teensy 3 compared to Tandem Non Stop 2 Mainframe

I am always amazed by how far technology advances year on year and I am glad to be working in the technology area. When I received my Teensy 3.0 I thought I would show it to my parents who have both worked with computers since when mainframes were really being introduced and worked for a company called Tandem. They produced the circuit board visible in the images which I believe is an IO board for a tandem non stop 2. For a full computer they said that there was a minimum of 3 boards required IO, processor and memory not to mention the connection to data storage on tape or hard disk platters. The cost of the board shown would have been approx £50k making the entire computer and installation cost in the £1million ball park. Comparing this to the Teensy 3.0 which takes a USB and pins to interface in and out it is just incredible to see how far things have come.

Teensy 3.0, Launchpad, Arduino and Raspberry Pi

Over the past year or so there has been an explosion of electronic development boards so you can build your own DIY projects and feed the hobbyists desires. I have been no exception and have quite a few boards including the Raspberry Pi, Arduino, LaunchPad from Texas Instruments and the latest addition of the Teensy 3.0. I have added a bit about each board and how I have used them.
