I've followed Tony's advice and went step by step, one board no chips,
chips loaded, second board no chips, measuring at each step. Finally
all seemed fine, I fired it up and now I've got RAM from 0000 all the
way to 7FFF :)
Next essential thing is the Load routine (from audio) that doesn't seem
to work. I wrote a routine to read bytes from the ACIA just like the
JBUG load routine does and simply quits when the first byte is read. It
loops until I start to play the audio file, so it actually detects that.
However when I make it loop until it finds a non zero data byte, it
never stops. So I thought all the analog stuff is working up to the ACIA
and the latter must be broken. Tried replacing it with no success so
far. Anyway, the kit is so well documented that I should have no excuse
of not being able to pinpoint the problem, learning a lot along the way...
Also, what are the best tools to encode/decode KCS audio ? From the ones
mentioned on the wikipedia KCS page I had success only with the perl
script, but that's only one direction.
