Sorry about the delay, here's the proxy code from our 2011 Twin Air before I swapped the TFT screen. 33 32 31 35 30 30 30 34 37 34 37 4F 55 54 50 55 54 2D 4A 49 54 20 10 23 digits in row 1-23 09 29 6F 04 00 04 02 00 00 00 09 00 00 04 02 00 00 00 12 C0 71 06 F4 23 digits in row 24-46 00 17 20 AA 80 0...

I don't need the Arbarth version on mine, just the 500T, I was just hoping to be able to switch between them to see which options it gave me.
I'll note the btyes down and post it up later this evening.

I've just fitted a tft screen in my twin air and have the same problem with Byte 65, no matter what I set it to it doesn't change the display.
