The Apple Macintosh SE/30 (1989)

The Apple Macintosh SE/30 was the fastest all-in-one Black & White compact Mac ever sold. Introduced in 1989, it is a very cool little system with big system features.

I was lucky enough to find a pair of these classic Apple computers at a garage sale, and for $5 each no less. In the video above we take a look at them to see what condition they are in after sitting for a couple decades. We also look at the effects of battery leakage on one board and test the use of WD40 to neutralize the leaking material through a process called saponification.

Fortunately there is enough here to work with so the next step was to test booting the machine. In order to do that we needed a working floppy so, in the above video, we completely refurbish one.

The main-board restoration had a bit of a hiccup but, in the end, we got it working as you can view in the above video.
