An Acorn 6502 Second Processor.
Its a bit yellowed but in need of a clean.
An essential upgrade if you want to play
ELITE at its most impressive.
Turn the unit over and remove the single
screw indicated in the picture.
Turn the unit right-side up again, then at
the rear, remove the 2 screws shown.
The lid can now be lifted clear.
Not alot inside considering these cost
199GBP when new and the BBC 399GBP
The inside has the usual "dust" everywhere.
Its abad picture but Ive drawn a cross,
with my finger in the dust to highlight it.
I have just wiped the case out and dusted
the boards with a vacuum and brush.
I did not strip this unit totally as some
of the wiring is a semi permanent
installation and I didnt want to
disturb it.
The rear of the case gets the same
treatment, ie a good wipe with a damp
cloth, NO cleaning fluids as they can
ment plastic.
The mains cable is wiped clean with
a damp cloth. Cables can clean up real
nice. Nothing worse than a gubby white
cable. To much "flash" in this picture
makes it hard to spot the dirty cable on
the left and clean on the right.
The top case was yellowed and in the
past must have had a book resting on
top of it as there is a patch of
"non-yellowing" visible. Also a paper
sticker at the front. Soak the case to
help lift the label and dirt from the case.
The case cleaned and wiped dry.
A bad picture as its over-bright.
I must get to grips with flash photography.
The unit re-assembled and ready
for another 10 years work.
