Let's go back and try to fix the LCD on that Amstrad PPC512. The one originally in the computer was shattered, so the plan is to swap it out with a working one and try to get rid of that ugly vertical black bar. In order to fix it we'll have to look at the voltage-generating circuit on the main board and we'll have to open up the LCD itself.

We'll wrap things up doing a light restoration of the Amstrad PPC512 by glueing the handle, fixing the hinges, and a few other cosmetic touches. In the end, it didn't come out perfect, but it's very usable.

Tune in for part 3 when we start taking it beyond the stock configuration and add some upgrades to make it much more functional.
