Thanks a lot for the welcome.
After a few weeks of reading and learning what is possible today my A1000 is now in a good condition. At least for me. I upgraded and modified a few things but i tried to keep the original feel. A few minor things had to be repaired.
The two main upgrades are the RGB2HDMI and the Parceiro2 with Accelerator. I got both from David Dunklee who is in my opinion a outstanding person. His support and knowledge is far above what you can expect.
What i still have to do is repairing my 1081 Monitor, the original Tank Mouse and cleaning the keyboard (it is yellowed in the front).
While installing and testing...
My current setup.
