These old Mac motherboards have cool 3rd party RAM boards (Mac's-a-million)

avril 25, 2024 Mourad ELGORMA

We have two Macintosh motherboards that were found in “left for dead” Macs that were reportedly completely rusted and destroyed. Both of these motherboards have period correct add-on RAM expansion cards which can introduce many more variables into getting the motherboards working again. Watch to see if I can get these two motherboards working again!
