So you like this this schematic correct? (Clicking the “up” arrow below)
I noticed there were several errors in the Advanced User Guide version of the keyboard layout. Some of these have been corrected, but the numbering of the pins to the eight input NAND (74LS30) is incorrect. From my exploration of the PCB I have modified the schematic from the New AUG.
Can you give an example of what you mean by every other key?
