Here is all you need to build this project.
MC-2G-1024.zip This is the latest version, containing 6 CP/M variants as well as Grant's NASCOM "ROM" Basic. Also included are 10 extra volumes with popular applications. See the .txt file for an index. system18.txt
This package is an extension on the FPGA multicomputer, as introduced by Grant Searle, which can be found here: <http://searle.hostei.com/grant/Multicomp/index.html>. It focuses on the Z80 CP/M computer described therein.
The system's main specifications are:
It runs on the EP2C5T144C8N Cyclone II FPGA and the configuration assumes it to be wired up as indicated on Grant's page. You should have wired up 2 serial terminals, an SD-card and at least 512k Memory.
James Moxhams Cyclone2 boards will work without modifications.
2 extra serial terminals can be wired to the touch screen connector, using RS-232 or USB converters.
You can also use a monochrome (RCA) terminal and 2 serial interfaces. In this case all unused signals need to be commented out. Examples of these configurations are included.
This package contains VHDL updates for
The package includes all binaries, source files, manuals and instructions for building and running the various operating systems, including tools for the additional features (disk mounting system reset etc.) Pre-configured images are included for system disks and Cyclone programming.
The OS specific transient commands are included as binary only. An Open Document Spreadsheet is provided to build custom keymaps.
