I have been spending an inordinate amount of time trying to find the owners of the old Digital Research "Concurrent DOS" operating system. There's a lot of interesting turns in the search and it's been fun to document.

I've written a blog post about it [1] though there have been a few updates since I've written that.

I honestly think it might be a fun thing for me to keep doing, whether or not I'm successful with my search. I think there is a lot of old software that is just sitting on old hard drives that is waiting to be preserved.
