I find isopropyl alcohol (2-propanol) plus a lot of

work better for dissolving stubborn dried tape and sticker adhesive on
plastic and some painted surfaces, but 'Goo Gone' (or WD-40) work well when
the adhesive is still sticky and active. You still have to remove any residue
from either Goo Gone or WD-40 with something like isopropyl alcohol too.
If the paint on a PDP-8 is soluble with isopropyl, my normal technique for
dried adhesive removal wouldn't be well advised at all though.
I'd be wary of using any sort of alcohol on acrylic/plexiglas/perspex --
it rapidly causes cracks and brittleness. See this:

Toothpaste and peanut butter might be helpful. The abrasives in
toothpaste are mild, but can frost glossy-smooth surfaces. Peanut butter
shouldn't do that. It might actually polish surfaces. In any case,
peanut butter is a handy way of applying oil and making it stay put.
