I guess I'm a pack rat, but I saved a copy of a ``crash'' clone back when I was running Microport's system V/AT on my 286. It was written by John F. Haugh II around 1988, with a copyright allowing non-commercial derivatives. As I recall, I compared it with the stock "crash" command that came with my system. It compared favorably, but since the stock version had a couple of more options, there was no reason for me to pursue it. It's system V based, but if you'd like a copy upon which to base a FreeBSD version, let me know and I can email it. Dave Bodenstab imdave@mcs.net
