 - The RCA jacks for the audio and composite video outputs have been replaced with some that can actually be found nowadays (i.e.: those that were used on A600/A1200). This resulted in relocating R409 (whose original position seems somehow improvised anyway...).
 - The above allowed a couple of tracks to be added so that the left and right audio channels will be somehow mixed whenever a single output jack is connected. This was lifted from the A600.
 - The silkscreen for some components does not match the original one. I used the built-in KiCad footprints as-is, when available.
-- The silkscreen and pitch of C303 and C304 have been made smaller so that they don't overlap.
+- The silkscreen and pitch of C303 C304 and C306 have been made smaller so that they don't overlap.
 - Speaking about the silkscreen, I have been quite liberal with it. I have used the default KiCad font and I did not follow the original label placement one at all costs. This was since today's technology can give us a bit more resolution in silkscreen printing, and I think that is worth using for the sake of clarity. Some ground stitching vias were slightly offset to make up space for labels.
 - The vias inside the pads of JP10A and JP11 have been slightly offset so that they are outside the pads.
 - The ground fill is autogenerated by KiCad, so it won't match the original exactly.

 The solder jumpers should all be preset with the most common value. You will only need to take care of JP4 if you install only 512k chip RAM: in this case DO NOT install U32 and put a blob of solder on the center and bottom pads of both JP4A and B.
 
+The battery holder is called BS-7 and is very easy to find. Other ones will fit just as nicely.

 Good luck! ;)
