This weekend I created stacklib.h - a single-header library that brings Forth-style stack operations to C. It implements a basic interpreter with: - Stack operations (push/pop/dup/swap/over/drop) - Arithmetic (+, -, *, /) - Output (., emit, cr) - Stack inspection (.s, depth) Example usage: Stack s; stack_init(&s); dict_init(); exec(&s, "10 20 + ."); // Prints "30" exec(&s, "1 2 3 4 .s"); // Shows stack contents The library is self-contained, requires no dependencies, and handles basic error checking. It was inspired by wanting to understand…

Hi! me and my friends together built an 8 bit CPU implemented in Logisim purely from scratch. The control unit of this system does not implement the generic microcode ROM or any kind of RAM. This was made purely from discrete logic gates and coded the system to run different programs. key features: Custom 16-instruction Harvard ISA, 8-bit fixed format, 4 general purpose registers Hardwired control unit built entirely from AND/OR gate logic matrix Dual-phase clocking to eliminate race conditions Bootstrap Control Unit that cold-boots via ROM-to-RAM transfer Early-exit conditional…

* OPEN TO CONTRIBUTIONS * NandToTetris is a course which has you build a full computer from: Logic gates -> Chips -> RAM -> CPU -> Computer -> Assembler -> Compiler -> OS -> Tetris All this is done via software defined hardware emulation. I'm building an emulator for this entire stack in C. How is my approach different to other projects that build emulators? - No external dependencies (so far) - Start with a single software defined NAND gate in C - EVERYTHING is built from this base chip - Don't use certain programming utilities: boolean logic operators, bitwise logic operators etc Instead…

https://github.com/siraben/ti84-forth Hi HN! For the past year I've been getting into programming in Z80 assembly (especially for the TI-84+). More recently I've been learning about the Forth programming language and after a lot of searching online (in vain) for a Forth interpreter for the TI-84, I decided to write one myself. It's been fun demoing this to others, because it's a very unexpected use of a calculator. It's my largest project to date, and I'm interested to know what the HN community thinks, please feel free to critique my code! -- Ben

https://github.com/siraben/zkeme80 As a successor to my previous project[1], a Forth interpreter that runs under the TI operating system, I decided to go all the way and write my own assembler and OS. This is a project I've been working on for just over a month, but there's still a long way to go. The idea is to have a kernel + the Forth interpreter and compiler, then users can modify how their operating system works through the Forth files. My Forth implementation is mostly ANS-standard conforming, so most code should work right out of the box without any problem. See…
