P.S. The HP Museum has the CE handbook for the 37 and Micro 3000, but
it's in the 3000 Micro XE section. You can find it by searching within
the Documents page linked at the bottom of the left side navigation

The red light on your disk drive is not promising I think, but you
should be able to get some output to the terminal before it tries to
talk to the disk.
You should have the terminal turned on before you power on the SPU. In
the video it looks like the latch mechanism on the terminal power
button may be broken as the button pops right back out and the
terminal does not appear to power on. If you hold the power button on
the terminal down does the display come up with function key labels on
screen etc.? If so, try turning the SPU key on while the terminal is
on (self test may take a little while, but it has been several decades
since I turned on a 37 so I don't recall exactly).
You can watch Lee Courtney's Series 37XE power up video on YouTube
which might be helpful.
