New PCB for M27Cxxx and MX29F1615

[kinmami]

Hello!
Thanks for the original idea and effort in the development.
I am currently designing a new PCB which will allow using M27Cxxx and MX29F1615.
I have added a relay to switch from 5V to 6.2V and changed to a fixed output LDO.
I am wondering if you have any further idea to improve the original concept and make this board better.
Of course, the intention is to preserve and broadly share your work.
Thanks & Regards,
Edoardo from Tokyo

I wonder if there would be a way to adapt both of your works to the OPEN SOURCE CART READER. This device can already program EEPROM and the creator tried to make it program 27c322 bu he lost interest before he finished to write the code.
