Hi all, To make it easier and maybe more fun for all, I'm sharing the PCB gerbers, BOM, schematic and top/bottom layouts. See here:
https://bitchin100.com/wiki/index.php?title=VT100#Build_your_own_MVT100 This project is basically a minor variant of the original design by Geoff Graham. To program the microcontroller you need a programmer, and you need to install the tools and learn how to program the chip. I suggest reading about the original project at: https://geoffg.net/terminal.html Have fun! Steve
