I have a feeling that we will not get any positive results. Fabio said that his machine is 8020/00 with TMS9129, but appeared to have S3527. I can not find any suitable schematic diagrams - those with 9129 are without S3527, but those which with S3527 are built with V9938.
Fabio, can you provide hi-res pictures of the mainboard you have?

i think exist a MSX1 philips with S3527 or other MSX Engine because POKE-1,170 is available for this model on MSX book

Fabio, is your goal to repair your MSX, or to collect a ton of documentation? If you miss documentation, use google to search for it - it is there. If you wish to repair PC, follow advices of the community and give results and feedback on your real actions.
Eugeny, this link doesn't found
This link should contain ".pdf" at the end!
