Nope. Both seem to be mostly non-responsive now. Must be contagious...
I don't know about Vince Briel, but Todd Fischer was never an easy guy to communicate with. I sent him a down payment for one of his IMSAI IIs way back when (2002?), and then struggled with him to get status updates over the years. After some years, he finally announced that he had had a bout with cancer, and it became more clear why he wasn't communicating, although I always thought it might have been easier to just put it out there in the beginning, rather than frustrating everyone who was wondering what was going on. Eventually, I did request my money back, and he did provide it back to me.
Since then, I have purchased his $99 copy of the original IMSAI documentation, but that was several years ago now that I think about it.
I, too, mightily wish that someone could get through to Todd and pick up the entire operation and bring it back to some sort of life again. I was excited to hear that Vince was giving it a try, but that petered out, too, without any real status updates, or any sort of information on what had gone awry.
Vince had an excellent reputation in the vintage computer community. Too bad he's gone quiet - that could easily ruin his reputation, too. I certainly hope that he is OK.
