I'd buy one for << 50

or a 2600 River Raid signed by Carol Shaw

That's sad. I subscribed a couple of months ago to support it but I guess my effort to help with edition 100 was not enough.

That's great because I want to interface them with NXP LPC2000 uC family. They are 5V tolerant and are powered by 3.3 V wich meets minimum Vih of 6507 (2.0 V). I hope it works

Just to confirm, these chips are TTL compatible, right?

Hey Chris, extend your Atari tour to Brazil

WoW... never seem that. It's a rarity even for brazilians!

It seems that you are using programmable logic in this circuit. Looks like a Xilinx device surrounded by other chip that I supose to be an D/A converter. If this is true, it's a great approach. Bugs can be corrected and features added by reprogramming the CPLD. Nice work! Wow. You have very good eyes! I took the photo in high quality mode, expecting people to actually *see* the board. But once again, I was defeated by the worthless autofocus. You are correct. It's a Xilinx FPGA and an Analog Devices DAC. There's some stuff on the bottom of the board too, but mainly just power and audio stuff and bypass caps for the digital stuff. Having the FPGA will allow me to support custom colormaps for those who prefer a non-standard palette. Bugs are certainly being corrected. But I'm pretty sure the feature set is locked now. Just a nice simple VGA board with a basic audio input and output for mixing external sources like the AtariVox. Maybe it's good that the pic is blurry. Everything on the board is hand soldered. Hand solder SMD is an art so you are an artist I wish I could use headphones on 2600 so I could play while my girlfriend is already in bed sleeping. Could include a TDA7050 or a LM4808? By the way, did you finish reverse engineering the TIA as planned in your 2001 proposal?

Tested on S-Video. The bleeding is very acceptable. Aparently it's working properly, Longhorn! Will post some pictures later

Mine is at the top row, second, left to right - Supergame by CCE. I also own a brazilian clone manufactured by Polyvox.

I'd transfer you the money if I wouldn't be located far away from bay area :-)

Year's Revenge - 30 min Asteroids - 30 min Enduro - 20 min Seaquest - 10 min Dragon Treasure - 10 min Tennis - 10 min played on a real console with a real joystick... what relaxing

Just to add a little detail. Working prototypes exist, so it's not vaporware. I have an alpha prototype and I sent one to Glenn. There will be a minor board spin and I wanted a second opinion, under the radar, before I finalize the circuits and open it up to beta testing. Clearly Glenn has a lot on his plate and I've been to busy to bug him anyway. But it looks like it may happen soon. That's great! As I said before, I volunteer to beta test it.

Any update on this mod, Chris? What's the actual status?

I'm having some bleeding on composite output (haven't tested on s-video yet). When I turn off color select switch the bleeding remains colored, for my surprise. Apparently it happens only to green. Any thoughts?

Back in my 2600 days, me and my friends used to discuss about games ending. We envisioned paradises, secret rooms and so on. Last week I found this on a brazilian blog; it's a joke on what a Pitfall! ending would look like

Have you happened across Jed Margolin's stories? He's a great writer and he includes lots of gratuitous detail: http://www.jmargolin.com/vmail/vmail.htm He describes the PDP-11 based assembler, binaries stored on paper tape, and home made ROM emulators. He also describes how the technology improved over time. Very fun read, along with everything on his site! - KS wow Very interesting! Here you go a fragment: Anybody else has more stories to share? PS: Vickey, having that scans would be great

Does anyone know what tools Atari programmers had on their desks to write games back in those 2600 days? What computers and assemblers (maybe in-house emulators) were used? What sort of equipment there were in Atari labs - scopes, multimeters, logic analyzers? How software and hardware debugging were performed? Just wondering

Everyone should have one of these: http://www.anatekcorp.com/blueesr.htm

I sent a question be asked to Mr. Bushnell

Amazing, after all these years and an Atari product was able to sell over 10,000. And this is without any of this being sold in stores. Viva Atari!!!!! I was wondering about this number of brand new 2600 joysticks. What a feat!

True - but my point was that you'd have to add active circuitry to convert the chroma/luma levels to RGB - thus defeating the purpose of RGB - the video isn't going to get any _better_ by converting it after it's been generated. -Ian Definitely! That's why we're interested in Longhorn's A/V mod. The act of modulating and demodulating the video signal is no longer necessary in the actual TV sets because A/V inputs are now a de facto standard and this process introduces unacceptable noise in the signal. Generating a RGB signal wouldn't improve noise ratio by any means. This mod is the best we cand do for the Atari 2600. I'm still waiting for my mod to arrive but I think it'll take longer to reach me here in southern Brazil. Congrats again!

Correction: Use space bar to fire, arrow down to deploy charges just like VCS. Sorry!
