Apparently the 600XL and 800XL keyboard tests spell out "Copyright 1982 Atari".

Hi Paul - Re the keyboard - It was the Self Test Easter Egg - As explained by Scottith Games on YouTube: "EASTER EGG: When running the full diagnostic test on a 1200XL, the keyboard will spell out the programmer's name, "michael colburn". This was removed with the 600XL and 800XL, with the keyboard test now spelling out "Copyright 1982 Atari"...

Here's Version 5.1... Happy Warp Speed Software V5.1.atr

Some pictures of my 1200XL. (1) Remove 4050 IC (U27) from socket and insert UAV. (2) Lift the back pins of L1 + L3, and run wires from to the vacated pads to UAV "Luma" and UAV "Comp Video" respectively - See Pic 1 (lower part) (3) Lift one side of both C103 and C104 - See Pic 1 (upper part) (4) Run wires from Colour and GND points - See Pic 2 (Colour is the lower point, GND is the upper point) to UAV "Color In" and "GND" respectively (5) Run a wire from the empty pin on the video DIN connector (J2-5) on the back of the board to UAV "Chroma".

I had the same issue when I put mine together last week. I overwrote the sdrive.atr with another one I found online and it then worked. Could be as simple as that.

Could I wait to effect the repair? Hell no. Did it work? Hell...no. I'll try burning a new EPROM just in case I damaged the "original" when removing it. PCB looks good. Just one bodge wire was required after careful analysis. Let's see what happens with the EPROM...

Certainly the same area of the PCB @Technoid Mutant, but my broken trace is the one next to yours!! The pictures are great. I've got enough to work with and will post how I get on with the repair tomorrow and, if not, Wednesday. Many thanks!

Many thanks, Jeff. Much appreciated. Agree about the eyes! Will PM you a bit later.

Here's a dump of the EPROM in case it is of any interest to anyone. AtariMaxHappy.BIN

Hi Paul, they certainly are. It's been a while. How are you doing?

Thanks for the speedy response @xrbrevin, but unfortunately my PCB has a different layout. I think there were quite a few. Pictures of my board and the damage :

I just did the same I had the bright idea of desoldering the EPROM and putting in a socket so I could experiment with Rev 1 and 2 Happy ROMs. Despite using my trusty desoldering station, I trashed some traces. Very minor repairs are needed to just a couple of traces bu after careful checks under magnification I just can't see exactly where they originally went. I've got the same board as @Technoid Mutant. Can anyone share a decent picture of the underside of the board, please?

Attached are all the Happy Warp Speed Software .ATRs I have found over the years. I think *only* Version 7.1 had a Side B (Documentation and IBM Xfer Utility + additional PDBs). Has anyone got any other versions they can add for posterity?

Thanks @DrVenkman. Crystal clear. What you describe is how I understood things. All this talk of connecting to "lifted ends" was confusing me a bit! Perhaps "vacated vias" would be a more accurate description of where you have to solder the connections. I connected mine up exactly as you did, which is in line with the original instructions at http://atariage.com/forums/topic/246613-new-video-upgrade-coming-soon/?p=3432251. I'm not sure if I ever saw the photos showing (incorrect) connections soldered direct to the lifted ends of the inductors themselves that you refer to, though.

Just wanted to clarify matters around the connection to the "lifted ends" of L1 (Luma) and L3 (Composite) on the 1200XL. The original instructions early in this thread were to connect to the pads vacated by the back pins of these inductors and not to the lifted end of the inductors themselves. Did anyone try / get better results soldering direct to the lifted end of the inductors?

David's formatting issue discussed in the following thread turned out to be caused by U21 (3086) http://atariage.com/forums/topic/265289-drive-reads-writes-fine-but-wont-format/?do=findComment&comment=3757248

Really pleased you got it fixed, David!

I had a similar issue and got lots of help here back in 2015. It turned out to be U21 (3086). http://atariage.com/forums/topic/239200-another-strange-1050-fault/

Recent posts reminded me provide an update on the sticker I was trying to replicate. The attached JPG is as close to the original sticker I could get in the end (and it is very close). The attached PDF has six stickers on one A4 sheet. I had good results printing on to A4 glossy white self adhesive paper. Happy Switch Stickers.pdf

Super Zaxxon!

Congratulations on your newly acquired Atari goodness! Are you holding down the "Option" button when you turn the 800XL on?
