Hi,
I got a Tektronix TDS5104 scope from a flea market and brought it back to live.
That was easy, actually I only had to replace the CMOS battery on the mainboard an reconfigure the mainboard bios.
It is not the B version, but an early version with windows ME.
Unfortunately it lacks all options, I want al least the advanced math option.
Is there any information how to create the installation code or some other method?
To pay 8000$ for each option for a 20 year old oscilloscope is not an option...

I could get a brandnew highend scope for this money today.
I searched the web and the eevblog forum, but I could not find any really helpfull information about this topic.
