One more thing, it looks like there is serial with terminal:
Code: [Select]
# /etc/inittab
console::respawn:/sbin/getty -L  console 115200 vt100

Unfortunately, I hesitate tearing down my unit to confirm this (the scope is too lovely and too expensive).

I opened the scope once and poked some test points on the side under the LCD (probing the other side is trickier as the battery has to be plugged in) with the scope but didn't notice any UART.
I would prefer to avoid opening it too many times, as the front bezel is mounted on plastic latches and the LCD is held by screws directly into the plastic - both things might wear out. That's why I got NanoPi 2 Fire for experiments as it is the same SoC, just with more RAM and gigabit ethernet.

Interestingly, on tear down from Mike I see TO1104 equipped 2+1Gb RAM. Meanwhile I see only 256Mb available to the OS (but I may be wrong). Looks like the rest is reserved.

It is (in my TO1074 scope) the K4B1G1646I chip, which is 1Gb and two of them = 2 Gb and that is 256 MB (third chip is for the FPGA). So no difference from Mike's teardown. However, he still got a pimped-up scope as the seller knew who he was. For example, he got 2 speakers and 2 fans, while in mine I have one of each.

OMG, I was pretty sure I have two fans as they are bloody noisy :(. But after your comment I checked and found I only one!

Could someone on next tear down measure fan parameters (like size, voltage and possibly airflow)? I want to replace mine.

That's weird. I have a TO1074 (with 28M/100Mhz license) and it has 2 fans and 2 speakers too. My guess is that yours is missing something?

Maybe after some complaints about the noise, the company decided to remove one fan to make it less noisy?

What about removing one speaker?  >:D

I think you're right, they do it just for decrease the noise, for the reason may be a single fan is enough to cool down.
To be or not to be, who care this question?
