Here is a link to an interesting project I happened to stumble upon called "My4th". It is a very small homebrew computer design running a Forth operating system. The ALU is a simple one bit NOR gate. BTW: I noticed the PCB for building this project is available on EBAY. Michael http://mynor.org/my4th

Hi, I saw the PCB for this project on EBAY and could not resist. This little Forth SBC was easy to build. The parts to fill the board are available from Digikey. Here is a photo of the completed SBC, and an example of the serial terminal splash screen. Michael

Looks good, but I see a minor problem that it uses a EPROM. If the PCB could be adapted to use a EPROM or a EEPROM you would have more build options. Note I can't see part numbers here, just the UV window on the ROM. |

Looks great! I see complete kits available in EU (and shippable to UK, Norway, Switzerland, NZ, Australia, USA and Canada...) |
