| One Forth block consists of two microSD sectors. No filesystem is involved, blocks are mapped direct to the sectors: block_number = sector_number / 2. Caution! If you write a block on a formatted disk you will destroy the filesystem. Block 0 for example is the Master Boot Sector, to overwrite this sector/block would end in a disaster. If you really want to share blocks and filesystem on the same disk you have to create an additional partition for the Forth blocks. Or if you only want to play with some toy blocks, you can abuse the boot loader, because it is usually not required and you can therefore use blocks from 10 to 100. But be warned, do not do this on the SD card with the vacation pictures! The blocks can be used as buffers. As long as you use less or equal than 4 blocks, nothing is stored on the SD card. | ||||||||

| VI or EMACS keybindings? VI has a line editing mode too, fine for really dumb terminals. | ||||||||
