Probably some kind of clock patch. Cubase modification maybe?
Yes booting to the OS is normal. You can go from there on..

Yes. And if you are looking for the clock battery, this is inside the timekeeper chip next to the clock patch. When the batteries are empty you have to replace the hole chip (eg. with a Dallas DS12887A).

Yes, a socket is a good solution, I did that too.

I have a VERY SIMILAR mess in my Falcon too!

I was under the impression that its actually a FIX for the SCSI issues when doing D2D in CuBase Audio???

The thing is, that the mess made on my board is a disgrace and I have to now remove it to get my CT63 running properly.

To keropi

Sorry man, I missed your post it seems?

No, you do not need to remove it. You need to keep it there if its been done, leave it.
It was suggested to me, to remove it, but I was given incorrect information, and it shoul;d have been left there.

However, the person who did it, clearly made a huge mess and it does ned sorting out anyway, so now its gone, Im at least going to get it done properly.

To Puppetmark
Thanks, thats the one yes.

Just to mention here that in my TV serviceman times, I saw similar 'patches' in almost every Sony TV. Factory ones. Just components soldered.

Yes, thats the very doc I also have.

I have however decided that I will send my Falcon to Rodolphe, as I have a couple of ... Shall we just say "Features" that I am not overly joyous about... Im sure that Mr Czuba will be the best person for me to get to iron out there "Features" for me.
