开源软件名称:74hc595/Ultim809开源软件地址:https://github.com/74hc595/Ultim809开源编程语言:Assembly 83.4%开源软件介绍:Ultim809 Homebrew 8-Bit ComputerMatt Sarnoff (http://msarnoff.org/) The Ultim809 is a homebrew 8-bit computer built around the Motorola 6809 processor. It's a full-featured home computer with color graphics, sound, and support for game controllers and PS/2 keyboards. It won two blue ribbons (Editor's Choice awards) at Bay Area Maker Faire 2011! Full feature list:
I am making the schematics, design files, and source code available to anyone interested in learning about the project, or constructing their own. All material is made available under my (very simple) msarnoff.org license. Schematics and PCB layout file are provided for use with the open-source gEDA suite. Be aware that board revision 0 has errors: I have provided instructions on correcting them by cutting traces and adding wires. Ultim809 currently has no working mass storage, so a PC with a Unix-like operating system (Linux, Mac OS X, etc.) and command-line skills are recommended for working with Ultim809. You'll also want a 5 volt FTDI USB-to-serial cable. No microcontrollers or programmable logic chips are used, so an expensive programmer is not required. The 8K EEPROM can be programmed with a simple Arduino circuit. The 68B09E is still available from Jameco and other electronics retailers, but you'll probably have to buy the TMS9918A and YM2149 from eBay. Directory structure
