This is the 512k ROM 512k RAM Module which is supplied with the RC2014 Zed and RC2014 Zed Pro. It is designed to run RomWBW operating system on a RC2014 computer. Due to the 64k addressable memory space of the Z80, this module divides the memory up in to multiple 32k pages.
The 512k ROM 512k RAM Module uses a RC2014 Standard Bus. This makes it compatible with all RC2014 backplanes.
What is RomWBW
RomWBW is a ROM-based implementation of CP/M-80 2.2 and Z-System for all RetroBrew Computers Z80/Z180 hardware platforms including SBC 1/2, Zeta 1/2, N8, Mark IV, and RC2014. Virtually all RetroBrew hardware is supported including floppy, hard disk (IDE, CF Card, SD Card), Video, and keyboard. VT-100 terminal emulation is built-in.
The RomWBW ROM loads and runs the built-in operating systems directly from ROM. It includes a selection of standard/useful applications accessed via a ROM disk drive. A RAM disk drive is also provided to allow temporary file storage.
Wayne Warthen, the author of RomWBW, has ported this operating system to the RC2014, and it will auto-detect either the 68B50 ACIA or the SIO/2 UART. If available, it can also use Compact Flash or IDE hard drives for storage. Support is also there to detect and use a RTC Module or a YM2149 sound card.
