Would like to check it on DG1022Z as soon as it arrives.

First, create a USB drive with magic value "80 DF 20 10 90 20 62 80" in sector 0x58E0. You can format a drive as FAT and copy keyfile.bin from the attached zip to it. The keyfile is filled with the magic pattern, and the chances are that it gets placed over the right sector.
After that, insert the drive to your DP832 and send the following SCPI command to it.
--- Code: ---:PROJ:SET MODEL,DP832A
--- End code ---
Reboot, and you should be greeted with a colorful display.

Tossu and TV84, I cannot thank you guys enough for your help with this project, along with everyone else who provided insight and tried helping in hacking this! This was something I wanted for a very long time and just found out today that it was finally hacked! THANK YOU GUYS SOOOOOO MUCH!!!!!!!!

They appear too uneven in brightness when deactivated.
The combination I'd love to see is the font of the DP832A mode but other colors - even monochrome as in the DP832 mode would be ok.
Maybe the RGB values can be found and replace in the binary. ^-^

THIS! As much as I like the DP832A font it would probably take some time to get used to the new yellow, purple and blue colors. A firmware hack with a different palette would be fantastic. What colors would you guys prefer to have instead? IMO plain white for all three channels would be nice 8)

Actually, the choice of the color palette like it's been on the "non-A-configuration" but with the fonts / layout of the "A-classic" would be my favorite. Anyway, I'm happy the way it is right now. :)
P.S. I've also been playing around with my DG4102 and the prepared USB disk. Same result as @RoGeorge. Also somewhat strange behavior of the LXI interface via telnet but that's probably the result of the completely different underlying hardware (BlackFin) compared to the DP800 series (i.MX28 processor).

White would be my favourite too.
