± Electronic Symbol-Font II ±        |––––––––––}
History
=======
This is the first upgrade of this special elcectric symbol font First upload was at 2.5.1992. I added the 36 point size and enhanced most of the characters especially in large font sizes. Also some rearrangements were necessary because some symbols (mosfets) have been added.
What is this font for?
======================
This Font is based on the monospaced Monaco font. It allows you to draw elctronic circuits within only textbased programs. I created this font especially for "Dr. Circuit 1.4" and for PSpice. Now it is possible to show the circuit to be analized together with the description of the circuit. This font now comes with three point sizes: 9 points, 18 points and 36 points because it gives better output on ImageWriters, Deskjet printers and LaserWriters. This is only a screen font, but I'm working on a Postscript version. For all of you who own a LaserWriter and can't wait for the PostScript version I now created the 36 point size font, because the LaserWriter will scale down this font size to 9 points so you will have best output on your Laser printers. Personally I use a Deskjet and it works fine.
Installing within Dr. Circuit or in PSpice
==========================================
All you have to do is to start the Font/DA Mover and copy the Monaco font to "Dr. Circuit". In order to do this you only have to hit the option key when opening "Dr. Circuit". That's it!
Now you can use this modified Monaco font just the same way as the original. All the normal text characters are unmodified. Only the special characters now show the elctronic Symbols. So you can draw circuits and write text on the same page concurrently.
Installing within other programs
================================
TeachText and other text programs normally use Geneva 12 points as screen font. You can trick the system and use the modified monaco font. Therefore you have to start ResEdit and open the FOND resource (with get info), rename it to GENEVA and change the ID number to 3. Then you have to open the FOND resource the normal way, also change the ID number to 3 and the font numbers to 396 (for Geneva 12) and 408 (for Geneva 24). After that change the name of the Font family to GENEVA. At least open the FONT resource and also change the font ID´s to 396 and 408. When done the names of the fonts automativcally change to GENEVA. After that you can install this new GENEVA font inside TeachText or any other Programm that normally starts with the GENEVA font. These programms now show this modified MONACO font at startup. When you want to install the font into the System under its own name (say "ELECTRIC" for instance) you have to do the same procedure but only eith another FOND ID number and with other FONT ID numbers. So you can use it together with any application.
Where are the special keys?
===========================
All of the analog symbols are avaliable by pressing the option key together with another one. These are the positions of the electric symbols:
– opt - ± opt + fi shift opt 5
¡ opt 1 “ opt 2 ¶ opt 3
¢ opt 4 [ opt 5 ] opt 6

Additional notes
================
I you want to print this document out you should first install all fontsizes in you system file for best printer output, because I only installed the 9 point font into this "DOCter" document.
You can draw boxes with the connection symbols. In the first version of this font I placed those symbols in a quadrat around the h-key for easi remembering their positions. Because of the addition of the mosfets symbiols I had to clear this positions. As an easy alternative I placed them on the number keys. Perhaps you have to train a little bit with the output symbols for the Op-Amp, because they are a little bit tricky. I had to solve the problem that the output wire of the Op-Amp has Another height than the input wires. The opt space allows you to double the normal space. Most of the symbols have other widths than the normal characters (6 points). But their widths are always multiples of 6 so that the font remains to be monospaced in this extended way.
I hope you find this font useful for your needs. If you like, you can post me a note on GEnie.
Please notice that this is my first upload and I'm not very used to write in english, because I´m a german guy. So please overlock possible mistakes I made in this short info.
If you have suggestions, questions for this electric font, please post me a note. I'm very interested in your experience with my font and it will help me a lot to make it even better if you think it is worth to do this.
