Many have asked me, because that was my first real computer fonts and many times I've answered that this is my font Schwaben Alt. If you mean a font with a computer font that is used on a PC, then this is correct. But if you think any digital computer font under Font, then that's not entirely true. So my first real computer writing was actually only one file from many hexadecimal digits that represent the pixels of a matrix font. And also because this font was not stored on a hard disk or a floppy disk, but in an EPROM, a programmable memory devices as the sitting font ROM in an electronic measuring device. I was employed at the University of Applied Sciences in Hamburg and we had purchased for us the lab a digital recorder Fast Company GOULD instrument. And then we had the problem that this had only the English ASCII character set, and the German umlauts not allowed here because pose. I then sat down with the German representative of this company in any way and get a guide on how we could even create our own font ROM. And just as my first digital font is created. A font like seven point series is, in which a single letter up to five columns wide, so 5 x 7 pixels. Here I have now modeled such a font, with a far more developed character set but without conscious company consisting of a maximum of 5 times and only 7 points.
