I just pulled the hack on a TDS3012B and a TDS3034, both where a succes. For the TDS3034 I borrowed a TDS3EM ethernet module from work, they don't use it in the weekends. For some reason my Chrome browser wasn't able to display the web page, Firefox had no problem. Anyone else has issues with Chrome.
At first I made a mistake setting the TDS3012B to TDS3064B, it displayed the right version but on doing the SPC it failed and since there is no TDS3062B I had to downgrade to a 5 model.
Personally I love the TDS3000 series, it has been my daily driver for at least 15 years and it has helped me on many projects. It's very reliable in it's measurements even when running it for days and the responsiveness is almost like an analog oscilloscope (which I have much too many
). If you can pick one up for a nice price you won't regret it.
