Yes I have noticed that with rev1 cpu the voltage oscillates a lot more than with the rev6, it frequently drops below 3.1V.

Your TF360 is the only one not using the TBTorro power supply. Maybe that is part of it?

Nice to see there is a cool reg solution for the 3.3v. No more burger cooking hot, or was that the CPU :lol:
I hope you guys are writing down what WhichAmiga says the CPU's are rather than what's printed on them. Would be interesting to know if any 'reprints' are found and what they look like. As I previously mentioned, Motorola/ Feescale chips look to have 3 different types of print. Reprints all seem to use same type of print and the surface looks too pristine (like it's umm had the original surface ground/removed!!).
Thats probably a completely separate topic... if not forum :)

I assume you guys saw my page on it...

But you cannot tell by print anymore. I've had batches of 060's with exactly the same print on them, and some REV1 , some REV6. Only way to know for sure is to boot them up and check what it reports back in hardware.

I dropped back to the original TF360 firmware, as I realized that the one with the speedier IDE was a bit more unstable than the previous one (and also it wouldn't run at 50 mhz). This is probably no longer relevant since the rev1 PCB, but I just thought I'd mention it, in case it can help Stephen with rev1 debugging.

Chucky had the Faster IDE running at A34 for a whole day. This was at 66mhz mind. I’ve not found a CPU that would run at 66mhz yet.

Hows this for a dilema...
2 vias or swap the pin assignments and break firmware compatibility...

Stuck in bed with a nasty cold... Finished the TF360r2...

Almost all passives are on the bottom. I'm going to do a run of 10 on this one and see what gives.
Anyone got any idea how to extend the clockport?

What was the decision? I would have swapped the pins and broken compatibility! :) It's only Chucky, alenppc and supaduper after all ... :lol:
