One of the biggest problems with these old electronics are capacitors. If it isn’t the battery that’s gone dead and leaked all over, it’s the caps that are either out of spec or have already exploded. These machines can be brought back from the dead, and in recent months and years we’ve seen an uptick in the number of restomods hitting the Hackaday tip line. If you have a soldering iron and the patience to do so, any machine can be brought back from the grave. Writing for ByteCellar, [Blake Patterson] asks an interesting question: what experience do vintage computer enthusiasts have with dried up capacitors? Nearly every week, it seems, Hackaday gets another tip about a repaired or restomodded piece of hardware. There are always two problems. First, the battery leaked everywhere. That’s almost to be expected at this point, and if you’re very careful and very good, the damage caused by either AA cells or exotic ...
