  1. Hello everyone I'm in the process of building a VCS based hardware clone from scratch and have a few queries; I am going to replace the 6507 with 6502 (to get full 64k addressing + hardware interrupts + phi 1 and phi2 clocks ) and adding 32k of extra ram like the super Atari project (site is down but thanks for the wayback machine http://bit.ly/2FHlAH7) But these "NEW" eBay 6502 cpus (http://ebay.to/2DzjYJC) should work, or are these new chips like 65c02 in that the silicon has been altered due to "modern manufacture reasons"? And what's the highest clock speed available on a 6502? Also can you place some asynchronous buffer sram [cy7c408 = 128byte sram fifo memory] (http://bit.ly/2HGAAlm) between the data lines on the tia and 6502/7, so that the when the TIA Is drawing the data is already in the buffer, and all the cpu needs to do is correctly send the corrects address locations relevant to data stored in the buffer? (i.e instead of cpu calculating the display every scan-line you simply write a few scan-lines of image data into the buffer before The TIA begins to draw, then just correctly address in the order of whats stored in the buffer and do program logic) Since the [cy7c408a] is dual ported with asynchronous R/W, means you can just clock the output data [DO0-DO7] bus with the 1.19MHz clock from the TIA, iirc the TIA doesn't tend to like bus speeds higher than 1.19MHz? Then this should allow one to overclock the 6502 with for simplicity of counting cycles a multiple of the [ntsc] color-burst [TIA] clock ( i.e being able to have 684 cpu cycles per scan-line {using a 6502 clocked @ 10.75MHz = ~3x the TIA clock } instead of just 76 cycles) in such cases also sacrificing [native 2600] compatibility for increased cpu speed and more time for crunching instructions. I would also assume having the TIA reading the buffer @ 1.19Mhz would present in situations a bottleneck as well (when "drawing" to the TIA)? Since you can write data faster to the buffer than its being read (if the CPU is overclocked)? Since it seems the cy7c408 operates similar to a giant shift register, once its written you have to wait until data to reach to the TIA before it you write new data?? Can you just fill the buffer with 128 bytes of scan-line/sound data for the TIA, then handle the TIA addressing, and just fill the buffer as its being emptied, and essentially have 128 bytes of "VRam" (well more like Video buffer)? Also Can NMI be used instead of RDY, so that when the tia begins a new frame, wsync simply have the TIA tell the 6502 to "Stop, Pause , Go and do Display routine and then come back here", instead of just halting the cpu? Aswell i have a few microchip and avr (atmega8515) mcu's laying around wanting to be used for something and with a both MCU's, it's instructions are pipelined so that it takes effectively 1 cycle to load and execute data or decode and execute an instruction, except iirc when changing the program counter which iirc takes 2 - 3 cycles, So you don't have wait states [i.e iirc if using a z80, thats takes 3+ cycles for most of its instructions which is why they have such high clocks]. Is it possible to use the atmega or 18f4550 as sort of display controller for the TIA having the MCU handle reads from the buffer instead, and handle writing the data to the TIA, and use the atmega8515 to emulate the RIOT? Is it possible to emulate the Riot but with 256 bytes of ram? iirc RIOT ram is in page 0 so is faster to access than the 32k of extra ram? Plus is it possible, using A12 and A15 with a 74hc138 and a logic gate or two as a way to partially decode address to swap between cartridge space and 32k ram, so one can simply keep some compatibility, simply if A12 is high and A15 low then cartridge ROM is accessed, and if A15 is high in any case 32k Ram is Accessed? just building it to just play 2600 games isn't really hard (it was done from 1977 to 1992 literally millions of times), and seems a little redundant to me, I just figured since you can build your own 2600 compatible hardware clone for less than $50 in parts shipped, why not beef it up for some shits and giggles like a dev kit, have 256k of rom space and 32k ram, 6502, if possible using an MCU or 2 as an "In Hardware display Kernel", as well as emulate the riot, And CO10444D. why you ask? Because i i'll have the only atari "super" VCS with full USB 2.0 support (upto 12Mbit/s if I do use the 18f4550 lol) and plus i can really push the hardware to the limit see what it can do with some actual "power" behind it

  4. Hey guys, I am hoping someone can help me out with determining the value of my 2600. I bought an original 1977 Heavy Sixer at an antique mall/flea market type establishment, complete in box with the manual, warranty card, both original joysticks and paddle controllers, and all the cables, except for the switch box to hook it up to a TV. I purchased one of the coaxial adaptors so I could play it. In addition to Combat, it also had Riddle of the Sphinx, Starship and Air-Sea Battle in the box when I got it. I'm considering selling it, and I have no idea what it is actually worth. I would feel like a douche if I overcharged for it (I don't trust ebay prices as a guideline for anything) but I also don't want to give it away for too cheap either. I'm looking to either get a few more NES or Master System games instead, as I don't really care about having Atari hardware. I have an Atari flashback, and I love all the games on it. Any input would be most appreciated. Like I said, I have no idea what a fair asking price would be. Hope you experts can help me out! Thanks guys!!!!
  5. Well good news I found a heavy sixer for $20 at goodwill today. I was pumped till I got it home and started it up. Nothing but a black screen! Well I tried all the obvious stuff. Still nothing so I opened her up... No obvious problems. After a few hour of tinkering and checking voltages I decided to pull out my light sixer open it up and 1 by 1 I swapped out the socket'd chips. Bingo the little one in the middle fixed it. I didn't want to swap out the guts completely cuz I figured then its just a light sixer in heavy sixer clothes. But my light sixer is mint and the heavy sixer looks good but the wood grain has got some marks and the orange trim has definitely taken some wear. Now im considering swapping the tops. I know I cant fool the experts but I think it would make me happy to make my heavy sixer look perfect... But then again it wouldn't be perfect because I'd be cheating. What would you do?

  10. I'm looking for replacement controllers for my 2600 gaming. I have a pair of TG Enjoysticks, which are fantastic but seem to be on the verge of breaking. I would love to get more of the same but I've never seen them anywhere besides the original auction i got them from. Attached photos are some obscure items that appeal to me, in addition to the Enjoysticks. Some items I have for trade might include loose Vectrex stuff, Dreamcast console, Wii console soft modded for emulation, Game Boy games, Sears console, maybe other stuff. Or money.

    Hey all, I've posted about this before and got positive reception, so I'm trying to bring more attention to it. Any feedback is appreciated, although there's not much space left in the ROM for new features. This is an Atari 2600 homebrew game that's been in development for a while, and I believe it's finished now. It's a 4K, single player paddle game with SaveKey/AtariVox support. Plot: In this game, you must use the paddle controllers to steer your car left and right, avoiding obstacles in your path while collecting treasures. When you touch a treasure, you will get 1500 points and it will be added to your collection (the yellow dots on the left side of the status bar). You can have up to 5 treasures in your collection at a time. At any point, you can press the paddle controller's trigger to "burn" a treasure, giving you the energy to jump a short distance over any obstacles in your path. Any treasures you have left when your game ends will grant you an extra 1500 points. The game is won upon reaching 99,999 points. There are different kinds of treasures. Some of them will grant you unique powers: Gold coin: Does not grant any powers, is only worth points. Necklace: Gives you an extra life (the red dots on the right side of the status bar). You can have up to four lives at a time. Jar: Lets you pass through all barriers for a few seconds. Statuette: Lets you jump as much as you want with no penalties for a few seconds. The game will speed up when you get enough points. There will be a transition period where the game stops generating obstacles briefly, and the speed-up will occur while there are no obstacles on the screen. The difficulty switches toggle certain features. I highly recommend setting both to A for the full experience (Note: Stella sets both to B by default): - The left difficulty switch will make obstacles farther apart (B) or closer together (A). - The right difficulty switch turns moving obstacles off (B) or on (A). If the game feels too easy for you, enable Speed Freak mode! Simply press the game select switch at any point. When the title screen's background is red, this mode is enabled. Finally, the most important feature: if you press the paddle trigger while you have no treasures in your collection, you can honk the horn! Wow! As previously mentioned, the SaveKey and AtariVox are fully compatible for saving high scores (although there are no AtariVox speech functions). It saves unique high scores for Normal and Speed Freak modes. If you want to clear your high scores, press the game select and game reset switches at the same time.

  12. I recently picked up a 5200 4-port. It's missing several case screws. Can anyone confirm the correct screws used for the case? I think the screws that came with this 5200 are type b #6-20 3/4 sheet metal screws. Is that what it should be or perhaps these were used to replace the original screws that were of a different type? Here's what was in my 5200: It didn't have a power supply, but I found one elsewhere. It's an 11.5v version. I tested it with a multimeter and it's outputting 14.5 volts. From what I've found the voltage regulators in both the case and the switchbox should be capable of handling over 30 volts. Do I have any reason to worry about using the power supply? 3 volts over seems like a big difference, is that typical or should I start looking for another power supply? The traces (or is it the soldermask) on the back side of the board on is wrinkly (see the POKEY to C104 wire image below). Is that normal or is it a sign of something I need to be worried about? It looks like the VCS adapter compatibility mod was applied to this board, but I also see a capacitor between pins 1 and 17 on the POKEY and a wire on the underside between pin 1 of the POKEY and C104. Is this a known mod? Any idea what it's for? Trying to smooth out power to the POKEY perhaps? In the middle of the rat's nest that is the VCS mod, I see a resistor and a capacitor (?) wired in parallel from between the two resistors connecting R11 and C10 as part of the VCS mod. There's also a diode wired to either side of R10. Any idea what they're for? The parts side of the pcb, marked CA018087, has no revision. The solder side, marked C018085 is rev 7. I will probably apply the mod to separate the power from the RF. I was also thinking about doing the mod for composite and/or s-video, but doing that would make the VCS mod pointless, right? If I did the composite/s-video mod I could pull the VCS mod out. If I did that would I need to reconnect pin 24 on the cartridge slot to ground? Thanks for any help/information you can provide. I hope to get this 5200 up and running soon.

  16. I bought woody sixer vcs off ebay - it looks in mint condition, as do the paddels and joysticks. It doesn't have a power supply, do I need a genuine atari power supply, or can I get a multi adapter from maplin and use that? If so, which way is the polarity and what voltage should I use? I am in the UK. I am so excited!!
  17. I got a good sized collection so far even got some rare stuff. Rockin the Vader cus it’s the best vcs in my opinion.

  20. This one was based on suggestions from the community, and my own frustration with fast-moving games like Stargate that require two controllers. Two loose factory controllers are fine for the slower games, but unless you have a contraption that holds the two together, very frustrating for the fast games. Originally this was going to be for the Atari 2600 only, but a number of 7800 fans voiced a desire for one that would work with their favorite system, so why not? Especially with Robotron available on that system! The leftmost pair of buttons corresponds to the left joystick, and the rightmost pair to the right joystyick. The two toggle switches on the back shuffle the A / B buttons in each pair when used on the 7800. When used on the 2600, both buttons perform the same function. The two joysticks are digital, but have the smooth feel of analog sticks. Case is made of steel, so it's a bit heavier than the average controller, but well-suited for tabletop use. Felt feet ensure that your prized hardwood table won't get all scratched up. Too early to tell how many of these will be produced. Like what you see? Please contact me for any info not presented here. Larry

  23. I just found this youtube series of videos and I think they're quite interesting. It's from an old VHS, so the quality isn't very good, and I noticed a couple of inaccuracies about how the 6532 is wired to the joystick ports, but it's still very useful for someone learning how the VCS works and how to fix the most common problems. https://www.youtube.com/watch?v=wc6CYLFjKoo https://www.youtube.com/watch?v=5eGJdNxFuXw https://www.youtube.com/watch?v=0rxuD4mxBZU https://www.youtube.com/watch?v=jb6FZ8rB5gU https://www.youtube.com/watch?v=xBHKWYJAPyQ https://www.youtube.com/watch?v=uBVjD84nwNU https://www.youtube.com/watch?v=zLYGMrUJado https://www.youtube.com/watch?v=OvjdP79m4go https://www.youtube.com/watch?v=XD1Ci9L1AuM https://www.youtube.com/watch?v=tdh4vt8UEtI
  24. Hey everyone. I'm trying to get a general idea as to what joystick is great for the 2600. Any ideas? Thoughts?
  25. Updated: 1/15/14 Download: spctank.zip * includes source, 4k bin, manual, map, and label * Difficulty settings: Left switch set to A: more frequent powerups Left switch set to B: less frequent powerups Right switch set to A: slower non-player-characters Right switch set to B: faster non-player-characters Story: Two players (or single skilled player) operate a tank that has a command console with four functions (two joysticks). The left joystick moves the tank around and its button brings up the status display when held down. The right joystick moves a crosshair and its button fires the gun at whatever is selected. Their mission is to rescue prisoners of war from an alien planet. The prisoners are high ranking scientists of the players planet. The prisoners are being kept in a cell which can be found on the map included in this distribution. Three keycards must be found to open the cell and free the prisoners. The players tank has limited shielding and ammunition, but more may be found randomly throughout the planet. Players Will also find upgrades for the tank including the bigmissile and autolock. Alien enemies will be encountered most frequently and must be killed in order to find the keycards. Some aliens will require more ammo to kill than others, but the bigmissile upgrade allows for instant kills. The autolock upgrade causes the crosshair to lock on to aliens. Both upgrades have three uses. When the three keycards are found, the players should find the cell and free the prisoners. The players must keep an eye on their fuel level using the status display. If their fuel is running low, they must return the the ship at the starting position to obtain more. Types of alien enemies: Infantry Blade Saucer Bulldozer Powerups: Shield Ammo Bigmissile Autolock Structures: Ship (starting position/refueling) POW Camp Screenshots:
