Until you've used a TU58 to boot S/A BACKUP on

as part of the VMS V4.7 to VMS V5.0 upgrade, I don't think you've
lived :-)
Much more fun was the V2.4 to V3 upgrade on an 11/780. As part of the upgrade there
were two sets of microcode floppies and it was really important to get the right one in at
the right time. Failure to do so would lead to installation failures - but it took an hour
or so to discover that you'd had the wrong one in :-)
Even booting RT-11 on a TU-58 could take over lunch hour.
I could be shorter if the take was set up correctly.
The most fun I had with a real DEC TU-58 tape drive and
real DEC media was setting up a bootable Y2K version of
RT-11 on a TU-58 media, connecting the dual external
TU-58 tape drive to a PC via a serial port which had been
connected to a PC running the PDP-11 E11 emulator
on a Pentium 266 MHz system. It took just as long
to boot, but it was worth it the first time. That was
around 1997.
