The 8 main boards arrived today. Not packaged well. Several took shipping damage. Sigh. Second time I’ve seen this. I’ll never understand why people don’t care about this valuable hardware.

The 65kw boards have completely different checksums for all 3 of the main IC’s. So they may not swap with a 50kw board. Once I get them running on the test fixture I’ll then swap the chips over to the 50kw boards to see if they will work at all.

Most of these boards are P4 revision. Which means they are the second generation with all of the improvements built in from the first generation. I’m running a P4 second generation board in my truck for close to a year I think it is, and it’s never ever had a dropout issue. That’s a clue unto itself. My new spreadsheet is helping me to uncover the dropout issue.
