Hurrah! I have almost complete board. One small capacitor is still missing, I'm going to buy it after Easters.
I chose 0603 size of all passive components. Bad decision. Without hot air soldering station it is pure pain to solder 0603. Some of them are a bit crooked. But it is not so bad as may seem from photo.
What is on board? Well:
- MAX 10 FPGA 10M25SA
- 32MB SDRAM
- 16Kb I2C FRAM
- 256Kb SPI NOR SRAM
- MicroSD slot
- RTC
- RS232, PS/2, VGA, 10Mb Ethernet, Audio output
- Expansion connector
Next step is run MARK-II on it. It shouldn't be hard. :)

It looks great. MAX 10 is a lovely chip.
How many layers did you use for the board?
Are you sure? yes | no
It is four layer board. I designed it against OSH Park rules, so one can order them there.
MAX 10 is great FPGA, but only one PLL can be limitation. Also, if you want use integrated ADC, almost half of pins are unusable. Anyway, they are cheap and powerful enough.
Are you sure? yes | no
Neat. I'm working with a 10M16SCE144 at the moment, and I am trying to fit into 2 layers. Because I'm not using any of the analog features, and don't need low jitter on PLL, it should be fairly easy.
Are you sure? yes | no
The board looks really nice!
Are you sure? yes | no
Thank you! I cleaned it once again using isopropyl and now it looks a bit better. :)
There is new photo https://user-images.githubusercontent.com/17781503/38455173-8274c1d6-3a74-11e8-95c2-0bc5e3296400.jpg

Beautifull!
But I don't see mass storage on this board... no SD-Card? No flash?
Are you sure? yes | no
I forgotten. There is an SD slot under board.
Are you sure? yes | no
