So, up front, I don't know; I just wanted to share what I found.

 

First thought is that it's some sort of video mod since that square surface mount chip is the ULA.

 

Second thought is, perhaps that is just how they came from the factory. For reference see the motherboard picture here: https://www.old-computers.com/museum/photos.asp?t=1&c=634&st=1

 

Finally, this site might help: http://www.atkinsoft.com/ts2068.html

I think you're right that's how they came from the factory. I never had a 2068, but the 1000 I had was inexpensive. Not what we would call elegant by today's standards. 
 

Depending where you live, it might have been done for regional/export reasons. These were big in the U.K. but not anywhere else to my knowledge. 
 

I thought these two things were interesting. Disassembly video looks like your pictures. Repair manual has enough detail for you to just about engineer your own, but no photos.

Someone likes their hot glue... 

 

What is that long, orange component connected to the two capacitors?
