Yes, sorry. I guess you were doubting yourself? The download worked
like a charm! The only thing is that you reference EEPROM1 and 2 when
the files are 0 and 1... It apparently makes no difference what order
you do them because I did 1 first and realized there was no 2 :)
The jumpers worked out fine the first time. The pictures were great
so I didn't even count pins. I just looked at the traces and was able
to figure out where they went by that.
As far as the sockets, I don't think they're necessary, but I think
the first time you have to desolder 28 pins you'd be happy you had them.
So on to the functionality. Apparently only every other key on the
keyboard works now. Starting with low C it skips every other key. I
just was flipping through the programs and noticed something was
weird. What do you think that could be from?
