Great work SukkoPera

Jensma has done an A600 Ramexpansion for chipram last year which is open hardware too. But, better have two similar products instead nothing

Your A600 fast ram version is really great...why haven't you placed some holes for screws like the ACA620EC

I have an ACA620EC and have fixed it to the board with 2 screws. I highly recommend to add two holes in your design. One is directly near the CPU socket and the other one on opposite of the board. If you want to do that on your PCB it would be really really great and we get an excellent option. Without mounting holes it's not so good IMHO.

edit: Oh sorry, i've just seen you've added a screw hole....excellent

...still can be optimized with second screwhole on the opposite
