>I just checked the 060 user manual, and it says 4.9W at 66 MHz, which gives us 7.2W att 100 MHz => 2.25A at 3.3V. So the 8A figure feels a bit too high.
As I suspected.
Allowing 2.5A for the 060 and supporting logic, another 0.5A for the SDRAM, and 2.5A for the SV, total =5.5A. That leaves 4.5A spare, running the M1-ATX (which gives you 10A at 3.3V).
The Pico gives 6A at 3.3V so that would leave only 0.5A headroom unless you run the 060 at 66Mhz for another ~0.75A spare.
Personally I don't think people should invest in the Pico unless they are ONLT going to run the CT60 with the Ethernat. I think it's chancing it with the SV too.
To be honest, the Pico would be ideal if it wasn't so 12V heavy (7A!).

What's the anti-troll code?
That's your personal code to be able to add comments and messages on the dhs.nu site.
Don't have a code or forgot it? Fix it here.
