About

SIXFIVE/OS is NeuraWeb's own operating system for the Commodore 64. Its name comes from the 6502 family of processors that runs the C64 and its cousins. ZEROPAGE, its core, is named for the 6502's zero page: the first 256 bytes of memory, the fastest the processor can reach.

It is one of three worlds of Machina, with NEURA/8, the machines rebuilt with our own ROMs, and PETSCII, the board they call.
