MegaHomeFORTH

This is PCB for small Arduino based computer, capable of video output (VGA and RCA) and PS/2 keyboard input. It enables more modes of operatins - from simple breakout of atmega2560 with all pin available, USB serial may be added, also RTS/CTS flow controlls, output to VGA or RCA (which can be changed in runtime too), SDA card reading for file operations, extended RAM to 64kB is possible (and swap two banks) also it enables another 128kB RAM via port opperations and finally it can have gates for system bus and act as graphic card for another 8bit computer. It will also run specialised FORTH for HW testing and programming and as "operating system" At this time it is still under developement and testing and will take at least few month to be routinly usable in full configuration. Here is photo of prototype showing some FORTH screen, more photos will came after I will populate the card and make it work :)
