- The font from the C64 Dead Test cartridge is undocumented online, prompting this article to fill the gap.
- It uses a unique 58-character font inspired by the MICR E-13B set, with an Easter egg transit symbol at screen code $21.
- The font is implemented in an 8K Ultimax cartridge, bypassing the C64's built-in ROMs by using a special memory map.
- Character matrices start at address $EAD8 in ROM, with no reverse video characters, and unused codes display a fill pattern.
- The article provides downloadable versions of the font for C64, VIC-20, and PET computers, including a sympathetic lower-case set.
