Drawing schematics on a computer?

[unrealdave]

You can save from within - easily! This was a great tip thank you - thanks Jeff for your suggestion also but this is much more me. I have already done the first stage much easier than with paint

I have lots of valve type symbols (anyone want them let me know) that go great with this little program so as soon as I am allowed I will produce a circuit diagram for the neutralising set I am working on. Must go to the garden!
