Hi again.....

I have trying to figure out what some wires on my MB do.
Look at it, and try to explain.

http://pici.se/pictures/oHwyFyrgE.jpg

1. Shall this green wire be there on this LF347P? (#1 at pic)

2. These wires is not original what i can see. A GD74LS164 is "piggybacked" on top of the IC. Wire 9 goest to the MC68901P IC, and wire 14 goes to the Yamaha YM2149F.(#2 at pic)

3. TOS 2.06 SW (homemade by previous owner i think) NOT ORIGINAL!

I have noticed that the game "rick dangerous" booted with my other STe goes into 50HZ on my TV by RF OUT.
On this 520STe it changed the RF OUT to 60HZ. Is the wires on my mb a 60hz hack?

The other strange part is, if i boot up with the TOS eprom (tos 2.06 swedish) vertical lines is shown.
If i boot up with TOS 1.0 US, the picture is OK.

Can it be the TOS eprom chip that causes the lines?

Help wanted

Micke
