Every single of those numbers represents a test the computer realizes. From checking if the ROMs are present and are correct, checking if RAM is present and correct, initialize video and check the synchronization signals... Underlined means missing, reversed means faulty. No decoration means that the test succeeded. If you are more interested, I have another video in my channel that explains all of this.

Very cool

It always takes this much. The time will come for my 9404 C10, and I fear it will be longer.

Sorry, we haven't opened the computer yet, so we don't know about its hard disk drive. However when it first engages the headers it makes a very distinctive noise. About the diacritics, I don't know enough. As far as I know this is a Spanish unit but I have nothing else to compare it with.

I use a product called KH-7, usually employed in kitchens. If you are sure to clean the motherboard with water, first be sure the capacitors are discharged and after the washing dry it carefully. Also give it a time for the remaining water under the components to dry - otherwise a failure could be induced.

@@retroand Thanks, yes, just did some readin gon the topic and it seems drying with compressed air is a popular methos...in any case I'll give it time to dry :) Another question: Can you recommend a forum or similar to ask questions when I run into any issues with the restoration of this computer?

@@retroand Thanks so much! I'll skip the French one but the other ones I should be able to understand ,😃

@@tecnociclista5342 No, thank you. If you checked my videos you would see only two real conversations in the coments. It's nice to see people asking real questions about what they see.

There is only an instance of teleport in the demo I made, which was between non-adjacent rooms. Everything was implemented in a single scene, with each zone being an object with a tilemap. If made this way, I thought I could load and dispose of them programmatically althought that mechanic was not implemented. Each zone object contains all its rooms within its space and the room change effect is only an illusion - the only thing that changes is a limit imposed by a custom script into the camera bounds, clamping its position. I simplified the algorithm by making all rooms to be of a prefixed size (or multiple), at the practice behaving like the room system of th NDS Castlevania titles.
