I tried reseating the Indi and then my image had a blue tint to it instead of pink ;-) So I have soaked Lisa in IPA and I'm waiting for her to dry.
Yes I guess they are all very old machines now. Actually I'm surprised how good my A1200 mainboard looks though. (It's my original A1200 that's been in storage for years and I'd never even removed the shielding before). All the electrolytic caps look fine and even the lithium button battery in the expansion board still has some charge left! (the real time clock has actually still been keeping time all these years).
