A collector of vintage Apple computers is attempting to restore a non-functional Apple I to full working order, and is documenting the process on Twitter …

Jimmy Grewal was previously Microsoft’s program manager for the Mac version of Internet Explorer, but his present role gives him a handy advantage in his restoration efforts – as Gizmodo notes.

He bought the non-working board through a Christie’s private sale, for an undisclosed sum.

“The team there helped me assemble an Apple-1 replica last year on the off chance that I ever got my hands on an original […] that effort has paid off now as we have the knowledge, tools, and most importantly experience to tackle restoring something this rare and valuable.”

The latest news on the project is that it has failed electrical testing, but they haven’t yet identified the problem.

Should components need replacing, Grewal is determined to make the restoration as faithful to the original as possible.

Grewal told Gizmodo that he is selective in his collection of Apple computers.

Apple I models regularly sell for low to high six-figure sums, but Grewal has no plans to sell: his goal with this one is to display it at a museum so that as many people as possible can see it.
