Built for Electronic Shop Practices class. Used for most of the rest.

I do not remember what is built on the breadboard, and I do not recall what the phone jack is for - it isn't hooked up.

 

Nice looking, call it a micro controller trainer and keep on using it.

 

You can download the manual for the kit in Adobe PDF form here:

Takes a few clicks and typing in a code to foil 'bots, but there is no cost.

 

That's nice, I'm using a Heathkit et-3100 which is similar, you can learn a lot from these. Nice pics
