Licensing and Credits

This board is based on the schematic listed on the RC2014 website, which is in turn derived from Sergey Kiselev's Zeta 2 SBC (GPLv3). Please honour the licensing for any derivatives made of this board.

Symbol for the AS6C4008 ROM comes from SnapEDA.

Version 2

Fixed:

• D0 was not written into the 7474
• A18 was not connected on the RAM, due to a buggy (copy-paste error) SnapEDA symbol.
