Well, I am pretty well ready to give up. At this point, after several erases (using the different options) it is not longer even showing anything under available options in the installer. It pretty much does not work; which is a bother because I am planning to leave the country for a new job in a couple of weeks and I was planning to take it with me. What will be worse is listening to my "you are so dumb for having bought an Apple" friends gloat. The good part is that none of them know I was having a problem with it this weekend (I didn't tell them why I was not out riding with them, I just did not show up). I suspect the hard drive. I may order a new one. Will any 2.5" ata drive work? I realize that it is a neat total disassembly to get at the HD, I may fix the broken mouse connector while I am in it (although I may not. I would need to get a SMT soldering iron to do that). For all that, I may just take my mac mini. I am pretty sure that I can get a keyboard when I get to China and I was told that my apartment already has a computer, so that means that there is a monitor. The mini, itself, does not take a lot of room. It is a thought.
