Fonts of Old Computers in C Headers

Question

I need to get the bitmap fonts of all computer systems (like that with BASIC, handhelds, etc.) as C data arrays or raw bitmap files. More fonts, the better. I would need a site with the files or a way to extract them from the memory of an emulator.

I need much help, pleeeease! ;)

I need the links of the sites with the fonts or lessons on how extract the raw bitmap from the ROM while the emulator is running (maybe with BASIC program listings)? :)
