As promised in another thread, here are some pics of the internal mods I made in my 1040 STE during my short summer vacation:
Everything works like a charm.
Next step will be to install the STE booster, but it's another story...
Cheers.

Here's a picture from another forum which will help you connect the Ultra Satan internally:
If you plan to install Exxos' HD fdd kit, you'll have to move the flat cable on the left side, as seen in my previous pics.
Have fun !

Re: STE mods
Next steps done...
CPU is now socketed
and tested... Everything works fine. :D
Exxos booster is stripped off and ready for a fit:
But I'll have to replace the SIL resistors on the STE board first.
Need to find more free time to get the job done.

Re: STE mods
The booster won't fit on motherboards where the cpu is/was soldered to the motherboard..

Re: STE mods
Yes, I know that soldered CPUs were not compatible with your booster.
I just plan to mod my STE as IngoQ did and that's why I had to strip your booster off.

Re: STE mods
It is not recommend or approved a reliable method of installing the booster. Just because ingo got it working doesn't mean its reliable or will work on any other machines.

Re: STE mods
I ended up keeping the 1.5 STF-Booster in my STE, since it had such a nice small footprint. But the STE booster worked very well too.exxos wrote: 12 Sep 2020 09:00 It is not recommend or approved a reliable method of installing the booster.

Re: STE mods
Sure it has, but as Exxos doesn't sell it anymore, the only way for me was the STE booster.IngoQ wrote: 14 Sep 2020 13:21I ended up keeping the 1.5 STF-Booster in my STE, since it had such a nice small footprint.

Anyway, I'd like to thank you for your great post. It saves me from doing all the research you did (connections, traces, etc.). 8-)
Cheers.
