Polysix programmer section issues

2015-03-04 by radek.tymecki@op.pl

I'm repairing P6 that had battery issue. Most seems to work fine but still some issues appear. When i press 1-4 in programmer section everything is ok. when i press 5 then 1 ligts up, then 2 etc. what can still be wrong? write button doesn't work

i've exchanged both 74ls08n close to battery. one connection seemed to be not ok. now the whole synth operates as it should however there is still one issue remaining. when i save the patch it's not saving MG and ADSR info. they are random. what still can be wrong?

Check all of the RAM address lines to their source.The only thing that is different for different parameters 
being saved to RAM is the address.  If some are saved correctly 
and others are not, it should be related to the address.

Make sure you double and triple check for any more open traces. I thought I had them all the first time but I missed one. That one open trace was preventing the attenuator, EG VCA mode, and all effects from working.

first i've checked ram. i dont know what was it but pin 1-8 were connected to each other somehow... i found one bad trace on IC31 but it's now fixed. anyway i've re-checked all traces from IC30/31/32/22 and thay seem to be ok. maybe i'm missing something?
