Instruction Set for ECM-16/TTL homebrew cpu
Details from Instruction Set for ECM-16/TTL homebrew cpu
The instruction set for ECM-16/TTL homebrew CPU can be subdivided into several broad categories: - ALU operations on General Purpose Registers - MOVs - Loads of immediate values into registers - Loads/Stores via explicit (direct) address - Loads/Stores...

Clock driven by small homebrew CPU
Details from Clock driven by small homebrew CPU
For the Tell Time Contest, most digital clock submissions will be clocks driven by a microcontroller. This clock, however, uses a homebrew CPU from TTL chips to run the clock. The square-inch CPU only needs external ROM, RAM (the two big chips)...

MC68000 Computer
Details from MC68000 Computer
This project is a homebrew computer based on the Motorola 68000 CPU. Design includes four megabytes of RAM, 128kB of ROM, Something for video, two serial ports at 9600 baud, and eventually networking and a hard disk.The purpose of this computer is two-fold:...

Amaranth : PowerPC homebrew computer
Details from Amaranth : PowerPC homebrew computer
Amaranth is my main homebrew project at the moment. After mostly finishing up with the Motorola 68030, I decided PowerPC was the next architecture i would target. It uses a PPC603e PowerPC CPU running @90MHz, and features my FPGA VGA controller, Diapason....

Sugarplum
Details from Sugarplum
Proposed features: * 16-bit homebrew processor, may do some 24-bit ops.* 16-bit I/O port to ease doing a homebrew GPU.* 20 - 24 bits memory addressing.* 3+ channel sound, perhaps 3 square-wave channels and a noise channel. 4+ channels would be nice.*...

RISCoVite
Details from RISCoVite
This design is still very early, but I'm planning to draw design elements from my previous (unfinished) 68000 homebrew computer project, so for the moment I'm assuming a similar design aside from the CPU choice and will adjust as needed as I dig into...

VBCC Compiler - SPAM-1 Backend
Details from VBCC Compiler - SPAM-1 Backend
I need a C compiler for my homebrew CPU project SPAM-1.I tried porting GCC and LLVM but it's a hopeless task. Luckily the VBCC compiler is a hell of a lot easier to port and there are some other examples to look at.If you want to...

4 bit TTL ALU
Details from 4 bit TTL ALU
This ALU ( Wikipedia: ALU ) could be used as a building block of a homebrew CPU. It has not many components. It happens to fit on a one square inch PCB ! It could have been made smaller, using IC's that can only be soldered under a microscope,...

MKHBC-8-Rx
Details from MKHBC-8-Rx
MKHBC-8-R2 - Multipurpose 8-bit Homebrew Microcomputer. Design and Specifications. 1. Architecture of the system. The system is intended as a hobbyist computing/microcontroller expandable platform. The CPU of choice is MOS 6502 compatible microprocessor....

ECM-16/TTL homebrew computer
Details from ECM-16/TTL homebrew computer
Computer design goals: Architecture: RISC-like – inspired by MIPS, but is quite different. This is Load/Store architecture, meaning that ALU operations are only applied on data in registers, and for using data from memory it should be first loaded to...

Fast PDIP 6502 computer
Details from Fast PDIP 6502 computer
See also this YouTube video describing the way the system works: This is my attempt at making a fast 6502-based homebrew computer. The current prototype is stable at 32.768MHz, which I'm happy with as it's in the same ballpark as 6502.org forum...

Cobalt-68: Homebrew 68008 computer
Details from Cobalt-68: Homebrew 68008 computer
So far, so good... Hello, Hackaday! I want to tell you about my pet project aimed at creation of homebrew computer. I've been doing this project for three years. In this entry I want to briefly summarize what's been done. Why I'am doing this? Mostly...

HBC-56: 65C02 + TMS9918A on a backplane
Details from HBC-56: 65C02 + TMS9918A on a backplane
Introduction After building a breadboard CPU and getting it to run Snake, I decided to do something different. I'd done some coding for the Commander X16, so was interested in starting out with a 6502-based homebrew computer. My childhood machine...

Baffa-2+ Computer
Details from Baffa-2+ Computer
More Info: Baffa CP/M SBC2 Rev.0As the Baffa-2+ looks like an end product, why not invest in advertising? As seen on tv :D... The Single Board Computer is equivalent to the following set of Baffa-2 boards: Baffa-2 Full BackplaneZ80 CPUDual ClockDual...
