k-01 Emulator

Free, Easy (to use), and Portable is the name of the game. Through a clever use of C, this program will take a program written in binary for the k-01 architecture, and will run an emulator which will print the output of the program. Every aspect of this project was difficult to create. First, I designed and prototyped the k-01 CPU a breadboard, a simple 8-bit CPU similar to the 6502 (used in the Atari 2600, Apple II, C64, and more). Then, I wanted to write programs for it, but manually programming each op-code into the EEPROM was very tedious and annoying. I decided to make an assembler for it (k-asm) which takes a file that is written in the k-asm language and assembles it into a memory file. The memory file is then written onto the EEPROM and tested in k-01. However, small bugs could cause hours of debugging, so I created the k-01 emulator. It uses the original micro-instructions that the k-01 uses. Written entirely in C, this program can run on just about any computer.

k-asm Assembler

Closely related to k-01, k-asm is a self-contained language and Turing-complete, written in Python. An example program is included. A few features include: ability to read/write to and from ram, i/o pins, registers, and rom; binary, decimal, and hexadecimal conversions; numerous and descriptive errors with line numbers, warnings (coming soon); (too) many addressing modes, such as implied, absolute, accumulator, x, and y; over 50 op-codes, each with 1 or more addressing modes; conditional branching, jump if greater, equal to, or less than another number; comments; and more!

Math Website

A lightning-fast math website. Regular updates to pages. Covers advanced math topics from Calculus to Abstract Algebra. Utilizes Bootstrap and JQuery to create a mobile responsive web-page. Math-gurus love this site. It goes over practical applications of group theory in real life. I mean, how cool is that? It also answers the question, 'how much powdered sugar could I get on a donut?'. Wow, just wow.
