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

Back in the day, we ran VMS 5.0 on our 11/730, because
we needed a
machine to link our product against 5.0 to support our customers on
the same version. I also ran Ultrix 1.1 at an earlier time on the
same hardware. ISTR both Ultrix 1.1 and VMS 5.0 fit just fine on the
R80.
Thanks for the data point. 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. Boot
time was on the order of 5 minutes, down from 25 minutes. Best I
could tell, the console 8085 cached the directory block(s), so the
tape practically streamed as it read file after file. Without all
that seeking, it was down to the serial speed the tape and console
were set to (38.4kbps?)
38.4kbps is correct. 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. Wow,
25 minutes of tape thrashing must have been unbearable!
