1040 STE Bussed Resistor Upgrade Fails...

It is very questionable whether such mods are really necessary, I don't think so!

You are entitled to your opinion, but please stop contradicting my years of research in discovering problems and solving them just to go against it by your own personal opinion. When you have invested all the time and effort and work like I have, then you can have an opinion here. If you even bothered to check Atari's own mods they even upgraded the resistors on later motherboard revisions! What I am advocating is not much different. So please do some basic research before sprouting your opinions in the future. This constant bashing of my work has gone beyond incredibly tiresome now. This also applies to anyone else who keeps on having little digs at everything I do and say.

As you have exhibited this behaviour multiple times now, you can consider this your first warning.

When removing bus resistors it's extremely easy to break traces. I always recommend fitting sockets rather than directly fitting new resistors. This allows you to experiment with different values and also reduces the chances of breaking them again if you have to remove/resolder different values.

Using a socket sounds like a good idea for the above reasons, but what kind of socket?
"SIL turned pin sockets" perhaps?

Yes, exactly these @Pacman

I'll get hold of those then, so the Exxos SIL resistor packs I bought ages ago can finally come to good use!
It's one of those things I've been putting off, fearing that I might damage the STe motherboard while working on it. But with a good desoldering braid, flux and of course the SIL sockets I feel a lot more confident about it. And as you said: if the resistor values turn out not to work as intended I can always revert or try some other values as they're all socketed from now on!
Excellent advice!!!
