Thanks! I was pretty surprised when the boot messages started coming out on the DECwriter III!

I'm hoping that I'll find good stuff on that RL02 pack that's claiming to contain "VMS53SYS". > The other thing I did, for my own sanity, was I reordered the files on > the console TU58 into the precise order they were requested.

The fellow from whom I bought the VAX mentioned that the included tapes were "load optimized", but I haven't successfully read one without errors so far. Not that it matters with tu58em, but the images I'm using also appear to have been load-optimized, based on the order of files on their RT11 filesystems.
