As I understand it the marker was on the white paper
not the plastic.
If so it is unlikely to remove the writing without damaging the paper.
If this is the case, then the fix is very easy - cut a strip of white
paper the size needed to fit behing "IMSAI 8080" and place it on top of
the damaged portion of the existing white paper - Once the screws are
firmly in place, it will not move.
I recall Rich saying the marker was on "the silkscreen" which I took to
mean the transparent/coated film that covers the white paper and blocks
out "everywhere that shouldn't be white" ... if this is the case then
the marker has to come off, or the film be replaced.

Dave
