I recently completed a build of Jeff Tranter's build of the TS2 68000 CPU. It turned out pretty nice but has serious limitations due to the original memory map of the TS2 which only had 32KB of SRAM from 0x000000-0x007FFF. The PROM is located in the...
PARTS It will consist of the following parts: processor in the spirit of the #1 Square Inch TTL CPU a simple ALU (described here)some address registers (described here)at least 256 KByte RAM flash-ROM for booting VGA videoPS/2...
After exploring a few random online shops one day, run across a very interesting development board EFB-REV1.it is a Free RTOS dual-core 32-bit CPU, 520 KB SRAM,4 MB Flash Memory, CPU operating at 240 MHz. EFB-REV1 has inbuild Serial Interface (RS232...
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....
TOM-1 is a TTL-based processor with a small instruction set. The idea came from reading about projects like Gigatron and Ben Eater's 8-bit video series, as well as Verilog CPU implementations like nybbleForth. The design goal is to minimize chip count...

NOTE: COMIX-35 IS NOT MY PROJECT!The COMIX-35 is an open-source clone of the 1980s COMX-35 8-bit home computer. It uses the RCA 1802 microprocessor which is strange and slow but holds the distinction of being the first CMOS microprocessor. The "35" is...
I have made lots of MCU based circuit and gadget, but felt some missing piece of knowledge between logic circuit (TTL) and software programmable circuit, so CPU.This time I found a very nice Japanese book, denoting "how to make CPU by TTL"Its ISBN is...
NOAHCube The cube is designed to be an automation platform. In this case a center piece that can be placed on your desk. It will be the control hub for your home automation but also a development platform for testing automation ideas. The NOAHCube...
I was doing research for a new hobby project. I wanted to build a 68000 system on a bread board with I/O and possible video. As I dug deeper I started shifting towards maybe starting with an 8 bit CPU (6809) and then do the 68000 after. ...
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...
Many shortcuts will be taken to fit this into the allowed 1024 bytes. I do however expect to create a fully functional, playable game in the end with scoring, sound and color VGA output in 640x480 60Hz mode.The project will be coded in assembly, with...
I am going to build a board, that fits into the space where the circuitboard of the old Nokia 3210 sits. It will come with the same layout for buttons and LEDs. The screen will be replaced by a OLED display that is much more beautiful than the original...
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...
