Hello All,
I just started to dive into Mister and I have to say: WOW!
Amazing work went into this project and as far as I can see is Sorgelig the main coordinator. So Thank You Very Much! As well to him as to anyone else who made this possible.
The reason I went the Mister path is couriosity regarding FPGAs, the iCE40 was too "small" for me, and all the other FPGAs were too "professional", and to be honest too expensive, so I thought Mister is the way to go.
And the main reason is: You can do something "useful" with it. I grew up with the VIC20 and later Atari 1040 STF, so I deem it "useful" to go a little back in time. Soon I found out that the Atari ST port is a little underdeveloped, but there are plenty of other cores to play with.
A bit ironic seeing the main forum for Mister being the Atari-Forum.

I know it sounds a little bit ambitious to learn FPGA by reading the core sources, but I've learnt C by reading the Linux kernel sources back in the early 1990s.

I started programming with Commodore Basic, later UCSD-Pascal on Apple II, GFA-Basic on Atari, Turbo-Pascal on 386er as well as C, today I still program in LUA for World of Warcraft and Delphi/Lazarus for work.
I've setup already the Quartus 18.1 lite suite and was in fact able to program my first "Blink" application, so far so good. But when I tried to compile some cores, it tells me it can't output *.rbf files since the sources seems to use some time limited components, that cannot be compiles by the free version.
Am I doing something wrong, since I'm a newb, or is it working as intended? Do I have to use the $3000 version of Quartus to compile the cores?
My second question is the ability to remote use the board: I'm able to connect by ssh to the board. Can I install a window-manager to use VNC on the board and use the cores remotely? Or is it imperative to use HDMI and USB keyboard?
And my third question is: How do I restart the board? F12 can restart the core but not the board, ssh can use "reboot", but is there any keycode like Ctrl-Alt-Del (what doesn't work) to reboot the board?
And again: Thank you very much for the cool work that went into this project!
