Da wurde im Nachbarforum ein REU-Nachbau vorgestellt... REU plus2c
ZitatI already have a working prototype of an expanded version of this design called the REU Plus4C includes all of the 2C's features plus wifi, USB serial, VGA text mode display, and coprocessor. I am in the process of getting the FPGA code ported from the 4C prototype to the final-ish PCB and should have a working version in a couple of weeks.
Mal sehn wie das weitergeht...
