[NSRCA-discussion] Heathkits

[ronlock at comcast.net]

I'm still using a Heath ESV, one of the few that does single nicads.

Agree on missing the stores and the kits.  That was my introduction to Elec. Engineering and programming which has ended up putting a lot of food on my table over the past 20 years.

I used to live at the Heathkit store in Pittsburgh when I was a kid. Never
