Pretty much a 2600 with a full 6502, using the extra address space and Interrupts, along with a Atmega 8515 for bank switching and memory bank management, an atmega 644 (or 8515) as an extra coprocessor which will work similar to an antic chip, hopefully compatible with (most) stock 2600 carts, more or less a 2600 if actually designed around a home computer from the era, note this is a. Here is a project I've been working on over the past few weeks - a 6502 compatible single board computer with 128K of RAM, 128K of ROM and an IO expansion port. The item for sale includes only the PCB (printed circuit board). We are in no way associated with, nor do we represent, C= Holdings, the owner of the Commodore trademark. In addition to the processor, ROM, and RAM, this board includes all peripherals required for stand-alone operation including serial, parallel, Propeller-driven video output/keyboard input, and SD card storage. It features 8/16-bit data operations, functioning on an 8-bit wide data bus with 16-bit addresses (mapped via 2K-byte pages into a 22-bit physical address space). 6 Outside Dimensions 4 4 Disassembly and Assembly 5 5 Circuit Description 6 5. computer can offer such variety of uses and applications at such an affordable price. MKHBC-8-R1 homebrew 6502 computer - assembling CPU card. Skip the PCB for now. Z80 Microcomputer Kits I have for sale educational 8-bit computer kits which use the Z80 for the central processing unit (CPU). The MITS Altair is widely accepted to be the computer that first kicked off the personal computer age. Power supply and LCD information Details of barrel connector size, LCD, Flash ROM for microprocessor kits. You depend on measurements to make key decisions and discoveries. It fits directly in the metal-cage of the vic, but you. Free Next Day Delivery. Some time ago, Nick created a 6502-based breadboard computer that he calls the Vectron 64. Cheap mosfet 10pcs, Buy Directly from China Suppliers:10pcs AON6502 AO6502 6502 MOSFET QFN-8 Enjoy Free Shipping Worldwide! Limited Time Sale Easy Return. He wires the CPU, ROM, and RAM to a PCB and adds some logic gates for memory addressing. Made and assembled by Atari Printed Circuit Board(PCB). Pocket-sized 6502 coding!It doubles up as a 6502 programmable calculator, plays chess, and is a pretty good machine language learning tool. New old stock Rockwell 6502A (2MHz) CPU Ideal Replacement for 6502 & 6502A found in many 8bit computers These are 'new old stock' not 'pulls' and have been 'batch' tested by ourselves Acorn System 1, Apple II, Atom, Electron, BBC A/B/B+, Electron, KIM 1, NES, Oric 1/Atmos, PET 2001-8296, SYM-1, VIC20. This would be of interest to anyone who tinkers with old computers or arcade machines – I originally wrote about it as part of building my homemade 6502 computer. To connect to any other devices a 1MHz connector with multiple plugs is needed. Which brings me to the next topic, does it need to work? If it does, then a compatible 40 ping CPU need to be found. Except there is no Rev. The coprocessor is an ATMega1284P microcontroller that has several purposes: first it generates the necessary reset and clock signals for the 6502. The first West Coast Computer Faire in 1977 was a landmark event in the birth of the personal computer. This small computer is made of a 6502 CPU, RAM chip and a ATmega16 micro controller. Thanks to a burgeoning interest in electronics, I’ve become very interested in designing and building my own computer. Some time ago, Nick created a 6502-based breadboard computer that he calls the Vectron 64. Commodore Basic Beginners Guide 1983 5 Pages Reproduced March 17, 2004 from Transactor Vol 4 Issue 5 Fall 1983 with permission from Bruce Beach. The Atari 2600 also has ripple voltage on the CPU power line once it boots. While work and other commitments have been sapping a large amount of my time I have been making slow progress with the milling of circuit boards for the 6502 computer project. The KIM Uno is an Arduino (Pro Mini) based clone of the vintage 1976 KIM-1 computer. [Update May/13th 2015] Thanks to everyone who pointed out Ricoh is the company behind the original Nintendo NES cpu, a variant of the popular 6502 cpu.

It uses a real 6502 processor as CPU, and a real Static RAM chip as memory. What these parts did was supply a faster harder clock signal to the chip.
