I just put a few closeup pictures here: http://pics.lefauve.org/TH1/ I also added a picture of TH2 for comparison (that's supposed to be the same component) and a few pictures of the RTC (they really didn't put that much solder for this IC :o) )

In fact, last night I was reading "Hidden Powers of the TRS-80 Model 100" and they have a nice chapter called "The Clock-Cursor-Keyboard Background Task" which explain this in details :o) What would be a good place for ordering caps from Australia? (by good I mean trustworthy enough so I won't get cheap Chinese knockoffs, and if possible I'd like avoid paying a fortune for delivery). I usually go by eBay, but I'd prefer my new caps to last a long time without causing any issue. So far, fixing my Model 100 remind me of text adventure games from the 80s! Read books, find clues, read other books, test theories, find new clues, repeat until it works. I just hope I'll reach the end of the game :o) Eric PS: I think I'll try ordering a new TH1 too
