The level of personalized support and engagement David offers to Parceiro owners is just out of this world. I bought a Parceiro II for my Amiga 1000 (now upgraded to the latest revisions that adds a 68k accelerator and doesn't require replacing the onboard PALs) and had many issues with the board after recapping and replacing some chips. We must have exchanged ~50 messages back and forth; he helped with every bit of detail, providing suggestions on how to fix the issues, down to reading signals using an oscilloscope. I finally managed to get the A1000 + Parceiro working with his help.
His long-term plans for future versions of the Parceiro are also particularly exciting for owners who have PAL A1000s like me and can't have the Rejuv upgrade
Anyway, I wanted to leave some words of appreciation for David's work here. Getting a Parceiro for your Amiga is one of the best upgrades you can get. It is a great product and has amazing support.
