An Archimdes 310 keyboard for stripdown and clean. It is very yellowed,
I cant do anything about that but we can make it look better.
|
|
First turn the unit over and unscrew and remove the 8 self tapping
screws on the rear.
|
|
The rear cover can now be lifted off. Next unscrew and remove the
4 screws on the ends of the PCB and 3 from the middle, as shown.
|
|
The keyboard unit is now free from the case.
|
|
To seperate the key unit from the PCB, unscrew and remove the 21
screws shown.
|
|
The 2 halves will now come apart. Vacum out any dust from the contacts.
|
|
The keys can be pulled off one at a time, then wiped clean with
a damp cloth. Note the small rubber dust shield which goes under each key.
Refitting the keys is a pain as when you puch the key back on it tries
to pop the switch apart from behind. This is the most tricky keyboard I
have done. No more pics Im afraid as I run out of film on this one, but
re-assembly is not difficult.
