I started building my SRAM (256K) module. I hope it will work. Already have an idea how it will be mounted to the main board.

More to follow.


[UPDATE] later the same day.

These green pins with lovely green hats (I don't know how they are called in english), will be used to mount the module on the main board. If the module will work that is.

[UPDATE] @ 1.feb.

So, I did some testing regarding communication between cpu mcu and both mcu controllers for my ram. It worked. Could not yet test the ram itself though.

Red wires are address lines, yellow wires are Data in / Data out lines and three white wires are ram control lines.

Hehe, hat pins. That's wonderful :). Thank you for the kind words and for your comment. You are the first commentator :).

Strangely, the green pins with the lovely green hats are called "hat pins" in English, unless I am mistaken.

Great job on this project, keep up the good work! :)
