Subject: Re: [PolySix] Polysix Issues with: VCA / Octave Switch / Program 1 LED

Hi,

Make sure line DO0 terminates at all the places on the schematic where it is
supposed to (CN06, IC22, IC28, etc). The P1 LED will light on active low, so
that suggests this line is disconnected! Also make sure the latch input to
IC28 (P24, pin 5) is connected to the CPU. This track runs right underneath
where the battery spill usually occurs. Let us all know how you get on.

Cheers,
Andy
