TDS220 & TDS210 EPROM swap
« on: March 25, 2019, 01:07:00 am »
Is the only difference between the 220 (100MHZ) and 210(60MHZ) the programmed CMOS EPROM?

The IC #s, board layout, they are all identical. Absolutely no difference.

Has anyone ever tried to swap the eprom from a 220 into a 210?

One person tried the hack described in this thread, but it didn't stick even with a full re-calibration.
I TEA.

Good question. You wouldn't think someone would have hacked probably the most popular scope in history...

I got a TDS220 eprom and installed on a TDS210 board. 

The result is:
- Boot screen says it is a TDS210, not a 220.
- Boot screen failed the factory calibration
- When trying to self calibrate it exits the calibration procedure.

So the PCB has a 210 identification markup... now I have to find this thing...

On a similar note, what is the latest known firmware for the 210 and addon modules?

Is it worth the effort to upgrade firmware to a later version if it was available?
Any circuit design must contain at least one part which is obsolete, two parts which are unobtainable, and three parts which are still under development.

All resistors front and back around the processor block are exactly the same.  I will investigate more. Maybe something around the acquisition block?

Anyone with a faulty TDS 220 or 210 board to sell? So I can put it apart and proceed with my experiments?
