Just doing some more testing, as I wanted to see if I could successfully retrieve data from floppies with the system wanting to crash after a minute. I discovered something REALLY ODD. It crashes after a minute, BUT that is a minute after there has been no activity with the RX50. This is so wierd, however, if I can't find a solution, I think this is a behavior that I can actually live with. Besides since it sounds like this might be a problem with the version of RT-11 I'm running, I suspect I'm stuck with it. Zane | Zane H.
