Z80-512K is an RCBus and RC2014-compatible module, designed to run RomWBW firmware including CP/M, ZSDOS, and various applications under these OSes. Z80-512K combines functionality of the following RC2014 modules on a single module, thus saving space on the backplane:

• Z80 CPU Module
• 512k ROM 512k RAM Module
• Clock and Reset Module

In addition to these functions, Z80-512K includes programmable CLK2 clock divider, and optional support for battery-backed SRAM, power failure NMI generation, and a watchdog.

A minimal CP/M computer system can be built using Z80-512K module, an RCBus backplane, and a serial port module, such as Z80 SIO or MC68B50 ACIA. For a more capable CP/M system, add a storage module, for example Flock V2 Floppy Disk Controller and Real Time Clock module, or a Compact Flash module.
