nand2tetris Hilf Help Shimon!

I load a program into the CPU emulator and nothing happens.

Might need to drag the lower right corners south-east a little to see the status line - you'll probably see a message there. Why the hell they don't have a View > Parser Log through the Menu just beats me. But hey, it's free :)

Better nand2tetris. Please Shimon. Please Yaron.

In script ... illegal terminator '}' -- when your code doesn't even contain that character on that line. This happens when you run the HDLsimulator from the command line and give it an HDL file rather than a test script.

Why not provide an intelligent error message - ATLO perl saying ". Missing semicolon on previous line?" You get the idea..

Also, support for underscores would be nice. Duh :)

Qualcomm Snapdragon Boot Android

Can you use a bluetooth mouse/keyboard combo? Yes - something like the Logitech MK700/M705 work fine.
Do you *have* to use a true HDMI cable (no HDMI/VGA adapter allowed)? Yes (I know, shame on Q - R-Pi can do this)
