Eazy80 rev0 has been updated to rev1 which corrected all bodges in rev0 pc board. It is functionally same as rev0, but the three RC2014 expansion connectors are replaced with prototype area to facilitate experimentation with KIO. Homepage for rev1 of Eazy80 is:

One feature added to Eazy80 rev1 is an uncommitted 14-pin DIP for experimenting with 512K RAM and RomWBW. I have demonstrated that RomWBW can be ported to Eazy80 by replacing 128K RAM with 512K RAM, adding a SD card, and wiring in a 74HCT32 in the 14-pin DIP location. The RomWBW conversion is documented in this section of the homepage:
