bootLogo is a Logo interpreter with turtle graphics that fits in 512 bytes, the size of a disk's boot sector. Oscar Toledo G. wrote it in 8086 assembly in 2024 and released it under the BSD 2-Clause licence. This page runs it as a DOS program, translated to C and WebAssembly, drawing on a CGA screen.
Type commands such as FD 50, RT 90 and REPEAT 4 [FD 50 RT 90] to move the turtle. Keep it simple, because the interpreter is tiny. Always close brackets, keep procedure definitions under 120 characters, and avoid zero distances or repeat counts. QUIT, then Enter, returns to Volkov Commander.
