That big disk is nearly bullet proof, we had one in a store controller
where they had a fire in the store and the fire got close enough to it
to scorch the paint on the covers, but the drive still worked and all
the data was recovered off of it. They do however sometimes squeak a
little when they seek.
For the burn in on the CRT, only half of the CRT is used so you can
rotate it 180 degrees if that has not already been done. That also
works for 3741 key to diskette machine, same display unit.
The orange plastic box inside the cardboard box contains a head
alignment tool for the 33FD diskette unit. One thing that may go wrong
with the diskette drives is the lower limit stop on the head carriage
may break off and allow it to go below track 0. These drives do not
have a track 0 sensor so when they are initialized the drive does about
80 out steps to make sure it is at zero so it hammers on that down stop.
and it is plastic so it won't get better with age.
On the disk drive there is a head lock back top left should be locked
when moving and I believe there is also a spindle lock.
Those little cards in the envelopes may have been used for indicator
cards or probing. I seem to remember that the service guide sat in the
space just above the logic gate, but I don't see it in the pictures.
