DCO1 module tested with LPC2103

I decided to skip finishing the mother board before testing the DCO1 module with the LPC2103 development board. Instead, I tried to connect the DCO1 board directly to the LPC-P2103 board and assumed it would be placed at the lowest address so I wouldn't need the mother board to address the module specifically.

Added LCD connector to DCO1 board

Just a small update on the Matrix 1000 editor and some thoughts.

I realized I need a way to test how I should handle LCDs. Either I'd put an LCD on a new module, since I am thinking of putting two together to test the "motherboard" addressing somewhat properly.
However, lazyness got the better of me and I decided to just add it to the DCO1-board even though I am not planning to include an LCD on that board. Anyway, it will be used for testing only so I guess it's OK. I had a couple of free addresses on the board.

Here's a couple of photos of the DCO1 board in its current state:

Matrix 6 cleaned and keys fixed

Encouraged by the successful repair of the Matrix 6 I decided to disassemble the keyboard and try to get the non functioning keys working.
