Hi,
I have two revision 5 motherboard Amiga 500s. When I got them, both were pretty much identical ECS modded boards, installed with KS2.04 and fatter Agnus, OCS Denise.
But each board had a different motherboard modification done to it. Both mods were in the vicinity of the Denise chip. One was a wire running to a transistor(?), the other was the addition of a resistor.
Here are pictures (red highlights the mod) - click on them to enlarge.
What do these mods do - and why different mods for a motherboards of the same revision?
