Hey,

Just started to clean up my ste , and I’m curious about the mod you can see on the motherboard.

Anyone?

Factory bodge.

Thanks, so in layman’s terms this is just a factory signal clean up of some sort? What exactly does it do?

If you don’t ask questions you won’t learn anything :lol:

Not sure exactly what it does...but my STE with external blitter has it while my two with an internal blitter don't.

Might be coincidence, but I doubt it.

Would be great to know what it fixes... especially if it would affect what upgrades could be fitted!

Generally that white snot means a factory bodge.

It's this part of the schematic:

Prolongs the DMA sound interrupt signal.
