Noel Llopis did start 4 months ago a serie of videos about an Amstrad PPC 512 whose screen has suffered just a little bit... The videos are very interesting and my resume below cant show how interesting these videos are. Take the time to see them from start to end as I did.

• first video in which he will open the beast and trying to replace the broken screen with another screen from a PPC donor. Then he will use the CGA2SCART PRO made by Retro Erik. The CGA2SCART Pro permits to replace a CGA/EGA screen with a television using a SCART cable (RGB signal). Then he is running two of his msdos programs he wrote mayn years ago : Return of Frankenstein (3D isometric game) and Bouncing Ball
• second video where the screen will be repaired after many tests, a real work of a police investigagor but in electronics
• third video, it's time for upgrading (adding and testing a Gotek, adding and testing more RAM to get 640 Kb) and some reparations (the handle and the protection hatch at the back) to finish by dumping the spanish ROM of the PPC which wasnt available on internet, to be used with an emulator (MAME or PCEM)
• fourth video, the screen has been repaired but it's not perfect. So the original screen will be changed, two solutions being tested : MCE2VGA (which I use with my own PPC 640) and the GBS 8200
• fifth video, it's the part two of the fourth video where he is using a third solution to replace the original screen with a Raspberry Pi zero and the HAT RGB to HDMI which allows the use the HDMI output of the Pi (bare metal emulation, no raspbian OS used)
