As to Gschem - I'll take a look at it !
Glad you solved your problem. Several years ago I needed some circuitry done up that couldn't be done by any of the modern programs. Reason: recreating an ancient machine. Needed the symbology to match the originals. Found the solution on my Slack box. Between gcc and ghostscript, I simply wrote a series of schematic layout tools in C, and some symbol templates in Postscript. The C programs output the Postscript, which I could verify with gv. After everything was in order, I would just print it out. Rather time consuming, yet it has evolved into a fairly general purpose toolset which I use whenever I feel like dabbling with some homebrew circuitry.
