The standard idle pattern is in the data lights. I don't remember if the
"fancy" pattern appeared in V7.0 or earlier, but in any case it's an
undocumented SYSGEN option.
In RSTS/E, the display register shows the system error count. That's from I/O
errors reported by the various drivers.
Do you have a second disk pack? If so, you could use the DSKINT option in INIT
to initialize a pack, with pattern tests. That would show what the RSTS disk
driver thinks of your RK05.
Something else you might try: when you start the system, don't enter line-feed
for the quick start, but the START command. That is a more verbose version
which will display some additional messages. If anything is getting disabled,
it would show there.
