OK.. Not the jaws of a snake, but the
inside of the opened power switch
I removed the switch and the small
metal rocker to clean the metal contact
And that is the switch mechanism that
sits on top of the rocking switch
Those are the other components of the
switch which need a good clean
Rocker is now cleaned and placed back
Switch cleaned and reassembled
Note the small clamps that I opened
to the ends of the switch box to open
the unit and get inside
I have now closed the clamps
Next I need to clean the motherboard
Looking much better already
Places the switch back into the computer
Just slides in without any fixing
My goodness !!! She worked first time
And the red glow from the 3" disk drive
Sadly the drive wasn't working. Onward
OK remove ribbon, power, and two screws
and the drive is on the bench
Word of caution do not lose the write
protect pin. OK small screwdriver and
gently remove the first screw.
And then the second
Hmmm .. The third is missing. This is
a smaller screw and on all the drives
I have repaired has been screwed in
very tight. Maybe it was stripped and
left out. Dunno
There is sometimes a power connector both
sides. I can generally work with just the one
unfastened. Depends on the lengths of wires
Use a small pair of grips. Be carful and hold
the plastic and not the wires.
Don't forget to reconnect
Gently ease open the circuit board
Do not turn over or you will find
the write protect pin dropping out
It is on the left as you look from
the direction of the photograph.
In the words of Eric Cartman
' Hmmm interesting '... No drive belt
To the batcave and my bag of belts
They don't call me the rubber band
man for nothing. All belted up
Check your pin is still sitting quietly
You can see the write protection pin
just left of the hole by the connector
Just to give context as to where
the pin sits.
Clean and check the pully or capstan.
Left is stationary and right is with
me turning the bigger wheel. It is
going round which is the desired result
Time to grease the motor worm shaft
Filthy. Needs a good clean. Use the
correct cleaning fluid. Cassette head
cleaner is what I use.
Reconnect the ribbon and electrical
connection. Need to clean the case
Clean out the underside of the
disk drive bay
Connect the earth as you screw the
main drive back in place
Place the ribbon in the ribbon tidy
Power on ...
Drive light on and 3" inserted
Didn't work. Bugga !! OK cuppa tea
and let's have another go
