Charles Marslett, MYDOS and FastChip
Charles Marslett wrote floppy disk and hard drive drivers for Percom, and was the creator of MYDOS, a disk operating system for the Atari 8-bit computers that offered support for double density sectors, subdirectories, and hard drives. He also created FastChip, a hardware add-on for the Atari, sold by Newell Industries, that claimed to speed up floating point routines by 300%. He also created the A65 Assembler, a macro assembler. He has released the source code for MYDOS and FastChip.
