Try it once without turbo mode to see the turbo-mode detector. Then enable turbo-mode (by shift-clicking the green flag) and run it again to see the timer. Nothing else yet...
Thanks to @morveman for the idea for optimizing the pen up/down blocks. This is only 41 blocks as the compiler doesn't count - try deleting the sprite and it will still run fine! This is an emulator which emulates a SUBLEQ computer. Subleq only had one instruction: Subtract and Branch if Less than or EQual to 0. I have modified SUBLEQ a bit so it is now more like: Subtract, and store in a different location and branch if less than or equal to 0, else branch somewhere else, then read specific memory locations for IO.
