currently ver8 i think, but older driver ver7 i think. officially? you cant find dual core compatible driver from LeCroy, you only can find it here in this thread afaik... i kind of tired searching it, maybe its in page 4-8...cheers.

Hi analogRF,
I've upgraded my WavePro according to sergeyklenov https://www.eevblog.com/forum/testgear/upgrading-mainboard-in-lecroy-dda-3000-(aka-wavepro-7300a)/msg2655453/#msg2655453
But if you upgrade to the new motherboard without AGP - you can't use original graphic card and original LCD/touch screen (the original resistive touch screen is controlled by AGP card)
I've purchased 9.7" iPad LCD with display port adapter and with separate 10.4 capacitive touch screen. The only the problem, that 2048x1536 pixel LCD needs very fast (in 2D mode) graphic card
First I've tried Radeon HD3470 - by fast trigger XStream uses up to 33% of CPU (i5 3570) which is more then one core but XStream is unfortunately single threaded and most of 33% CPU usage used by system (red on the graph)
I mean it is used to transfer information to the graphic card. Now I've ordered Radeon HD 7790 and wiil try this card.
If you want, I can send photos of my LeCroy and detailed instructions.
Best regards,
Dimitrij

That's a big mess of a project that I wanted to avoid. Not worth it for me. So I ordered an Asus P5PE-VM and will put either a P4 HT 661 (single core) or a Core 2 Due E7600 in it. It has native PCI and AGP and is a drop-in replacement for the intel board.
In the meantime I think I have found the problem with the dead Intel motherboard (ADP3168). I'll try to fix that too. I just cannot let it go :box:

To do this lvds board 1024x768 30-pin scaler can be bought in China, but I prefer to to take out from the old monitor 15 ", which is sold for only $ 3-5.
So in the photo below you can see an example a more radical modernization. This mode 2048x1536 LCD matrix LTN097QL01 iPad Retina 9.7 ", which can also easily be installed inside oscilloscope instead of the original 10.7" NEC 800x600.
It is connected via DP (DisplayPort) interface and a discrete graphics card Radeon HD 6450.
I also last summer replaced the original motherboard WP 7300A to LGA1150, and processor Intel® Core ™ i3-4350, 3.6 MHz x 2 (4 HT). I spent a number of tests: it works faster than ever, and in some situations (in case of large number of computations) the waveform update faster to 4 times.

Hello, I have tried the LTN097QL01 with the HDMI2EDP-4Kx2K-V4.0 controller board (http://www.lcdparts.net/Files/MS609LC_Datasheet.pdf) , works fine but the HDMI2EDP-4Kx2K-V4.0 does not save the settings which has been made in the OSD menus within the HDMI2EDP-4Kx2K-V4.0 (like the language, brightness, etc...) when the +12 power is switched off! when I switch again, the default setting are there... Did you have better luck with another board?
Many thanks in aadvance!

I really love the Lecroy scope.
The DDA-5005 is awesome, however, only fixed 50Ohm input.
Simple hardware mod:
Bought a broken WP72000 :-DD
I'ts already up and running. Had a weird error where Win7k did not find a startup file. Cloned the HDD, now it works flawlessly.
