    3 previously unreleased 2600 games: Hobo, Spiders, R2D Tank

    in Atari 2600

    Posted

    Yeah, I wouldn't call them prototypes at this stage. They are probably better referred to as samples. I sometimes say 'betas' broadly for uncertain stuff. To call these prototypes is a misnomer. 

     

    I would also refer to the mask ROM red label Activision carts as samples. Most of the tiny label Parker carts are similarly probably samples as well.

    Announcing 3 previously unreleased (to my knowledge) games for Atari 2600 by UA, rounding out the sextuplet of games created by that company back in the day but never sold at retail. 

     

    Details about the three new games at AtariProtos.com, or just experience them yourself.

    Attached is the full set of six, with the three discovered games (Cat Trax, Funky Fish and Pleiades) being the same as previous.

    FS: Atari 800/810 ROM ICs in Atari Service packaging

    in Buy, Sell, and Trade

    Posted · Edited by ianoid
    added photo

    C011299 2 pieces 810 disk drive ROM $10
    C014599 3 pieces 800 US OS ROM $15

     

    Basically it's $5 per chip, but I won't break the packages up. They come in original Atari Service packaging, although the labels have come unglued, and the C014599 set originally had 4, but one was cut off and used, so it's only three ICs. 

    Will ship to anywhere.

    Photos of the package would help. I see a lot of overpriced Infocom stuff listed repeatedly these days. Is it the Grey box or folder version? Either way somewhere between $35 and $75 if complete with packaging and feelies.  These games sold well and so most aren't extraordinarily hard to get. 

    2 port repair question

    And I've worked on more than that and had to replace about a dozen of those chips over the past couple of years. So I don't know what to tell you in that regard. I actually like the stock controllers and yes I've also had to repair quite a few over the years. But it still surprises me how often I've ran into these 4052s being an issue as well. 

    I believe it!

    Excellent! Yeah... it is odd I've encountered more issues with the 4052 chips causing controller issues lately than actual bad controllers. Makes me wonder if in the past, how many folks blamed their controllers as not working on the controller when it could very well have been one or more of those MUX chips.

     

     

    That is not my experience or most people's experience. The controllers suuuck. I probably have found 1 perfect working controller to 10 bad ones. They all need work and rev 9 flex circuits. 

     

    This is the first unit I've had to fix the ports and I've had maybe two dozen.

    I was kind of expecting the chips to be like the Colecovision which correspond to one controller, I think, but after I replaced the other 4052, the unit works great. The 4052 failed testing on my chip tester pro as well. So problem solved. 

     

    Thanks for your help.

    FT: 2600 imports

    in Buy, Sell, and Trade

    Posted

    I have these 11 Canal 3 "Intellivision" PAL-M 2600 carts to trade. I'd consider cash offers, but I'd rather trade. Problem is, I have a lot already, so it's tough to find stuff I don't have yet. But if you have weird import 2600 stuff, whether it is from PAL land or Asia or South America, I'd prefer to trade for items I don't have. Ms Pac Man has a loose PCB and doesn't work. Smurf doesn't work but it is in very good condition. I didn't try to fix either cart. The rest are tested and work.

     

    Yes these came from a recent auction that gave me a bunch of titles I was missing that I'm keeping.

    So unfortunately the problem is still there. Weirdly with replacing the 4052 for the corresponding port, I get bad S/R and 4/5/6 (Pause is now responsive). Do I need to replace both 4052s? Is there crossover in their functionality? Port 1 works fine. I checked continuity on my socket and on the port. Another option would be just to replace the port. I tested all socketed chips including the Pokey using the Chip Tester Pro. I don't have a spare Pokey to swap out.

     

    Any suggestions moving forward to get this P2 port working a this 2 port 5200?

    Thanks. I just replaced one of those 74 series chips on a Colecovision. I ordered some of those 4052s from Console5 just now just to have around since they are cheap. I’d rather have the chip ready when I disassemble or else I’ll have another system in a state of disassembly at risk of misplacing parts and taking up precious workbench space. Fingers crossed it’s socketed.

    I've got a 2 port that has some issues with player 2. With known good controllers, Start/Pause/Reset and 4/5/6 don't work in port two. Port one works fine. I use a PAM diagnostic cart and Moon Patrol for testing (which is a good two button game).

     

    Is this typical of something I need to replace, like a chip, before I get this thing opened up? I know I need to inspect the port for damage and continuity.
