Thanks to both @Amstrad and @BLTCON0
At this point few things to reach the end, I've to do something with the hard drive holders as are also somewhat rusty, don't know if do the anti rust & repaint mantra to them or try to gather another ones in better shape.
Also retrobright of the plastics and finally an overhaul of a keyboard, I've three candidate Keyboards:
- The original one, SP layout, rubber cone type and with some keys that didn't work, also the case was very tatty & badly yellowed but the keys are ok as were all removed and stored on a drawer long ago (don't ask why :nuts
.
- An A2000 Keyboard internals (the one that I've used previously the lyra adapter that I use today) also SP layout and rubber cone type with some failing keys, this can be a good parts donor (for carbon contacts and such).
- An A4000T keyboard (A.Technologies), UK layout and metal springs type, some keys are dodgy, well this one can't be a parts donor as the key anchors and the carbon contacts are not the same than the previous ones but the good part is that the case is almost perfect, a bit yellowed but dent & scratch free so this will be the donor for the case and a perfect candidate for retrobright, it lacks the commodore badge but who cares.
Fun isn't it ? some big amount of patient and time will be needed again , this project is more like a penitence than a hobby.
