I recently bought three of them.
One for me and two for Xmas. ;)

i don't want this junk unless someone codes a demo for it

There have been several demos for 2600 (VCS) back in early 80s. ;)
6507 was similar to usual 6502 assembler, easy to code.
1,2 MHz, 128 byte ram, resolution 320x200...

there was also somekind of Atari 7800 'remake' which was in fact a NES-on-a-chip with conversions of the 2600/7800 titles on it *G*

But I think this one is a true 2600 remake (?)

Havoc: Ok, let's piss of the Amiga people again, this one will run on it :-)

Btw, alien, the 2600 is not that easy to code as you say it is, especially because it does not have video memory. It uses a "playfield" which is basically a 2-color mirrored background which you can control by rewriting a register just in time before each scanline if I recall correctly.

For those who are interested, there's a nice tutorial at:
Atari Age

It's a bit simple (it's aimed at people who don't have much programming experience I think) but it's a good read for anyone who quickly wants to get familiar with Atari 2600 programming...

o nice, the game device of my childhoot is back. Now we can play again a round phoenix, moon patrol "fuckin" pac man and all the other heroes...
Ripped one apart 3 years ago when they were sold in the states (by AVON, of all things... AVON is a sell-by-catalog-meetings-at-peoples-houses makeup sales thing.) There was no chip - just a blob of something inside a blob. So to actually put another game on it, or put a demo in it, you'd basically have to burn your own blob type crap.
Prolly easier to design a small circuit board that would output shit properly to the tv and fit inside the base of that joystick.
@Sparcus:
I know it isn't "that" easy.
I was talking about MOS 6502 or 6507 with less addressable memory in common.
The 6502 was born from necessity, because the 6501 was a 6800 knock-off and Motorola wasn't amused.
It was the time when memory was faster than the CPU. :P
This 6502 less register baby blew Intel's 8080 away.
The 8080 was followed by the Zilog80 but the 6502 took less clock cycles per instruction.

Even the keyboard controller in my beloved 68000 Amiga was a modified 6502. :)

Btw. nice time travel link!

@Truck: Greetings mate, you don't have to excuse for AVON. ;)

Cheers

The 6507 is not just similar to the 6502. It's *exactly* the same CPU, with a bunch of signals not bonded out (among other things the interrupt inputs and the 3 highest address lines), making it fit into a 28 pin DIP package rather than a 40 pin package.

And those sticks suck. For homebrewing, get a real 2600, slaughter a game cartridge (combat is a good candidate) and make an EPROM cart out of it.
