Any desktops/laptops/motherboards/SoCs that do not require closed-source firmware blobs out there?

Yep, and we non-niggers can't buy that. Too bad, it's excellent.
- coreboot
- amazing display (between e-ink and lcd, you can read outside)
- you can charge it with absolutely anything. DC, AC, any voltage, it will charge.

The tablet isn't that good. I should have been more precise: I was referring to the XO-1.
You can only find one on ebay for twice the price.

is there somewhere you can buy those for cheap? I'd like one for a DIY project

It's more expansive than the XO itself.

WOW WHAT THE FUCK. Seriously, I could buy a Kindle for 80$ and pay a neckbeard 120$ to reverse engineer the controller chip.

Try to play a video on the kindle screen.

I actually just want something I can comfortably read/write text (and code) on, colour not required. IIRC the kindle screen has a really crappy refresh, but I don't really mind.

I don't want whatever is displayed to go through the kindle. I don't trust their software.

If an Eink display is good enough, you can get a 6" B&W module for about $40.

Don't those require wacky custom interfaces to drive? Get ready to write some fucking low-level drivers for the GPIO pins on your dev board.

That's why you buy a controller chip with a standard bus interface and built-in waveform memory and thermal correction.

Interesting idea, maybe one could make a Lisp machine like that.

I'm pretty sure the Arduino is faster than a NES, and that's saying a lot.

>>196
Putting aside that ``the Arduino'' isn't a thing, you can't meaningfully compare different processor architectures like that.

Yes, you're right, I just meant from a general-purpose-computation point of view.

I read about people connecting their AVRs to DRAM chips but apparently the manual refresh takes up about 10% CPU power.  Maybe I could use a second AVR to do that?  Maybe I could use the second AVR as a system bus and memory cache as well.  Although 8 KiB isn't a lot.  Also, I'm not sure about the extra latency involved in memory accesses.

PIC, AVR and 6502 are in a much slower class of hardware. An FPGA would be much faster and more extensible.

Switch the design to use SRAM instead of adding a second processor for memory refresh.
