I got some inspiration today and did a complete set of 256 ascii and extended ascii characters.
Free to use but please provide credit since it was a grueling 4 hours in Ms Paint.

Some of the letters were very hard to fit in 8x8. Might be fun for maybe a very low res demo. They are currently monospace, however with some coding you could find the widths and use it like a normal font. They key to this set is the included border characters wich make it possible to construct crude boxes and such. Might be for for a ascii demo where you need some shapes drawn.
The file has a transparent background channel so it may be hard to see on the forum.
