It connected to the pins near JTAG. And it has title!

Yes, I realized that and pulled my earlier post in the meantime. But I am afraid the "version" resistors are there simply to let the software know about different historical board revisions, which may require slightly different software control. I don't think these will enable any options.

After all, one can buy software upgrade codes for the MSO scopes, right? As these upgrades do not require the user to re-solder any internal resistors, I believe that the options are enabled and disabled purely based on keys stored in EEPROM.

On a more general note, I must admit that I have lost track of this thread. Is there a proven method for enabling options on the MSO1000Z and DS1000Z-plus scopes? If so, could someone post a summary or a link please? Many thanks!

Gluk:
ebastler, Yes! Now I'm doing it. Some later I can post summary.
Or just see page #150, post by smgvbest

Ahhh, that indeed looks like step-by-step instructions, and nicely illustrated too!
Wow, how did you find that post in the 174-page thread?  :-+

Once you have confirmed that this works, maybe we can ask andyturk (who started this thread) to include a link in the first post.

I used the method on page 150 from smgvbest to "liberate" my MSO1104z-s and can confirm that it works.
