It was around in 1990. Then as far as I know, it disappeared, until I stumbled across it in my old comp.cources.unix file in an old archive tarball, and had to bring it back to life and up to date.
Yes, it has been. I've used it in the past (end of 90s) but I don't remember what for. Might've been some abacadabra like dd and fdisk on non-x86 or *BSD? I'm not sure. I actually forgot the name of this application, but now that I see it, I immediately recognized it.
