I went to the local big-box hardware store to get a new doorbell chime. I found one that was made by Heath/Zenith. When I saw that, it brought back a lot of memories about kit building in my first 20 years of life. While I was growing up, I built many Heathkits, from ham radios to test equipment to a computer based on the Z80 processor and running CPM.
So when I got home I googled Heathkit and found this website which brought back a lot of memories: http://www.heathkit-museum.com/
Now I find out that they are going to get back into the DIY kit-building business. It will be interesting to see what kind of kits they come up with. More info. . .
