  1. ...that the big alien mother ship IS virtually identical to the ship from the cartridge label for "Cosmic Ark" for 2600? Observe: Then there's the fact that there's a lander module, without which the mother ship cannot move... etc., etc. I laughed out loud when I noticed.
  2. I'm working on a portable Coleco project. It will be based on a regular Coleco board, but I'm cutting it off almost in a straight line just past the video chip. The existing 4116 RAM array is coming off, as is the video/audio switching chip (it sources either the Coleco or expansion module to the RF daughter board). Obviously, I'll also deep six the RF board itself board and P1 controller circuitry just past the gate chip. I'll be going back in with a TMS 9118 video chip -- which can use the "two chip" memory array formed by a pair of 4416 chips -- saving a lot of space. One benefit of this memory chip swap out is that the 9118 is a direct composite out and I'll be able to skip the RV conversion board and use the native composite signal. Finally, by discarding the original 4116 memory chips and the RV daughter board, I'll eliminate the need for +12 volts. I'll still need to wire in a -5 source for the negative voltage swing on the controller circuits. I'll rewire the P1 controller and after shaving the board elsewhere I'll be able to have a much smaller board (less than 5.5 x 6.75 inches). One of the other tasks I'll be addressing for the sake of space will be to replace those giant "horned" choke components with more modern (smaller) versions. Same with the large ceramic caps. I've constructed a miniature keypad (based on a mini calculator) so my portable will have full capability -I'm just too much of a Wargames fan to do otherwise. I even think I've figured out a way to wire in a rotary "gray" style encoder so as to make the steering games compatible. Video will be by the tried and true PSONE style screen. I've been working on it a while, and I have a supply of 9118 video chips and the two chip memory that works with them. I'm currently working on the first "mock up" to do a proof of concept using an uncut board, and on this I'll be getting my keypad and my rotary encoder cooking with gas. If I had not been so busy the last year, I'd already be much further along.
  3. The daughter board contains a chip which converts the color difference signals off the TMS9928 to composite. The TMS9918 chip is identical but puts out composite natively instead of using a color diff output. If you want to skip the RF board, the easiest way to do so would be to find a TMS9918A chip on eBay, clip pins 35 and 37 off completely (don't connect them to the board), and bend pin 36 up and to the side instead of setting it in the board. Tie Pin 36 to ground by way of a 470 ohm resistor. At this point, pin 36 itself will then supply a great composite signal. You don't even have to run it through DC removal or impedance matching as its all in the chip. This produces a great signal. But you'll lose video and audio from the Atari 2600 expansion module. Good luck.
  4. It is to my eternal regret that I did not, in fact, keep ANY source code or binaries when I left Beam Software. I was legally required to delete/return all work that I had done whilst working for them and since I was moving to a competitor, in effect, I did not want to leave myself open to ANY suggestion of impropriety. In particular, I deleted ALL software, tools, binaries, etc.. As I said, to my eternal regret, as some important work was lost for good. A few years ago I found a box of floppies that I'd missed, which had some interesting source code related to Bigfoot scrolling system, and some other stuff I forget. But of course these were kept inadvertantly and I have, of course, never distributed them. Note, I did not just TELL Beam I deleted stuff. I *actually* deleted stuff, because it was the right thing to do. To accuse me of "not giving a shit" is quite incorrect. I cared, but the moral and legal requirements were an overriding issue in regards to "keeping copies" of work done whilst I was at Beam. At the time I left, I thought that the game was going to production (it was the last game I did for them) and I had no reason to suspect it would be "lost" and never published. Cheers A Andrew, do you have your employment stuff from Beam? Your paperwork will make clear the biggest legal issue, mainly being whether Beam had authors like you standing as co-owners of the copyright, or made you sign on as "work for hire" situations, in which case you never had any copyrights in the game at all and produced it for Beam only. Even then, many developer agreements had clauses that abandoned projects (shelved or deemed unmarketable) would be assigned or revert to the author, so if you can locate that stuff you'll be able to see. If you were _not_ a work for hire situation (something Beam or its successor would have to prove by producing the work for hire agreement), then even if Beam took assignment of copyright, under the terms of the 76 act (effective in 78), you might be able to obtain full reversion as author 35 years from the date of creation. Of course, that's a long damn time from now. For the rest of you armchair experts, we'll have to agree to disagree. The fact that you take your reading of the scope of copyright law from the absence of "Goliath versus David" lawsuits just shows me you don't understand the marketplace or how these things work. Yeah, Nintendo and the other big guns are reticent to go after hobby guys who aren't seriously undermining revenues, but that's only because everyone remembers the Phill Kats / SEA lawsuit years ago and how those "PR" wars end up going. Its also because there are never lawsuits because the cease and decist letters are enough. Someone receives one, they take their site down, and that's it. There arent' lawsuits because no one fights them. They know they'll lose. Any of the sites named above would shut down immediatley if a C&D letter came. Hard to use them as evidence that its "OK" to distribute repos or copies without a holder's permission, it seems to me. Hey, to each his own. In this case all I can say is that I will vote with my $$ and will not buy a "repo" (even though I loved this game on the C64) unless its on a project that has Andrew's support. On the other hand, there are thousands of little copyright cases every year. Where the infringement matters enough to someone that they file to stop it. If Andrew can cobble together evidence to support a colorable claim that he's the copyright holder, he can get an injunction against reproduction practically at will. He's got the evidentiary burden of proving up his rights. But if he does so, its pretty much over.
  5. Thanks for the snark. I'm not surprised. The reason Nintendo does not generally screw with this stuff is that as a function of its overall earnings, repo carts aren't doing much. But if someone pokes them in the eye, they do indeed get involved: (See USA Today Article) Here, on the other hand, what some guy makes selling copies of the author's work with out the author's permission will be a number that represents a much larger percentage than a mere "drop in the bucket" (as it were) in terms of the Author's typical monthly take. Nintendo does not flatten those sites, but it could pretty much at will. And my view is that the brazen posts in this thread get the author over the hump in terms of proving willful infringement. See the news story this weekend about the multi-hundred thousand copyright award against the kid who shared twenty sings on a file sharing site? Alas, I guess you're right. Copyrights aren't ANYTHING to worry about. Have fun with that.
  6. If you want a copy of the ROM Andrew them PM me with the email address you wish me to send it to. I can't see why you shouldn't have it to be honest... Hi, Lawyer type here. I offer these comments in the nature of a legal commentary and not as advice to anyone. Get your own lawyers. You can't afford me. That said: The physical embodiment of the program in a proto cart is an interesting case. Normally the "first sale" doctrine would mean that an existing embodiment of the commercially sold cart can be sold, resold, and resold again without consent etc of the copyright holder. That one copy can be in anyone's hands. Just like used books, you see. However, its clear on its face that this program was never released to commercial channels. I'm not sure the first sale doctrine would apply. I'm not sure if the court's have confronted such a case. There are cases where a prototype of software or a manuscript was stolen in development and everyone down the chain had to surrender copies of the obviously purloined copyright material. For anyone down the line, the question is whether you're a good faith holder. You can't have good faith when you're holding a copy of Metallica's new album 5 months before the release date, for example. But here, its possible the proto was in the hands of a software house under NDA and limited try-out license, and then the software house simply collapsed or went out of business. There may be some interesting legal issues as to ownership of the physical "cart" itself. What I do know is that COPYING and distributing ROM dumps, or a "run" of cartridges based on the ROM would most certainly be subject to an injunction and damages by the author of the material, assuming he took revision of the copyright when the project didn't sell (typical 1980s and 90s development agreements usually provided a reversion of copyright to the author, so that the author could try to peddle the program if the software house refused or was unable to. My guess is that a decent copyright firm will consider this a slam dunk. Even if Andrew does not still have sole rights "Beam Software" is still around in the form of Krome Studios Melbourne and they might be inclined to stomp this sort of thing. What distresses me is that there is so flippant an attitude to screwing the author over here. As soon as he appeared in this thread, the guy with the cart made a transparent effort to have the author buy his own work back with others bidding against him. Now there's apparently another party in the mix who can't wait to have people pay money based on the author's work. Sickening. In my humble opinion this is what should happen if people were smart: The author should get a copy of the binary. He probably will probably be perfectly willing to leave the "proto" cart in whoever's hands it lands in, but will then be in the position (as is his right) to license such copying of the ROM or repro carts as he determines. Maybe he'll go for free broad release. Maybe he'll do the run of repros. His copyright, his call. But if people (not him) keep after this idea of releasing profit projects at his expense, he'll have to hire a lawyer. And in the end, it will get ugly. Go look up "disgorgement of profits" if you're thinking of profiting from a release of the game. My guess is the damages the author will get will be more than what is made (considering the wilful infringement will get him his attorneys fees). In the end, he'll probably end up owning the original proto anyway. As we say in my business, there's an easy way and a hard way to get to the correct outcome. Which will it be?
  7. Here's a link to the thread for the fist time I did the 4164 mod. I only had a short period of time, so I short cut it by piggy backing the 4164s on top of the 4116 chips and then depriving the 4116 chips of power. I tried pulling the choke coils to deprive the whole area of the board of +12 and -5, but as long as any of the power or ground pins of those 4116 chips were connected to anything it didn't work. So I came up with the result here. Not elegant, but it works great and wow its nice to not _ever_ have any issues with the power switch! http://www.atariage.com/forums/index.php?s...=135183&hl= I ordered my chips from an eBay vender. Here's one selling original NOS chips, and they're even "real deal" Texas Instruments! http://cgi.ebay.com/Nine-TMS4164-15NL-DRAM...p3286.m20.l1116 Good luck.
  8. Let me look again..... OK: A 74164 is a shift register. So is the M53364P. The other two look like samsung's connotation for memory, but they're missing the KM at the front. Call and make sure. If they are Samsung part nubmers, then they'll be the right thing: http://www.datasheetarchive.com/pdf-datash.../DSA-570564.pdf ETA: I highly recommend that you replace your chips with sockets, and then for a "test" run (without changing anything else) just order a set of 4116 chips to drop in and see if anything else is blown. It is POSSIBLE (though unlikely in this design) that if your +17 bridged something internal in one of those 4116 chips, that voltage may have crossed into the TMS9928 chip (the video chip with the heat sink) in which case, good luck.. those are harder and harder to find.
  9. If your +12 was really only +17 without a load, you may have lucked out on the LM1889 in the RF Modulator box. (My datasheet says 18v max). Negative voltage circuits are touchy, and forgive me for saying, probably beyond your skill (that's OK, I screwed up a dozen before I figured it out). Permit me to suggest a shortcut: http://www.dimensionengineering.com/Negatron.htm Ben Heck used it in his Coleco portable, and I will as well unless I figure out a substitution in the controller circuitry that obviates the need for negative voltage swings. Now, look at the price there. Permit me to suggest your best option is to hit eBay and grab a new power supply. In fact, for probably a few more bucks you can get another Coleco that hasn't been blown all to shit. Finally, as to the 4164 chips, these are the guys you want: http://cgi.ebay.com/RAM-TMM4164AP-15-TOSHI...p3286.m20.l1116 Make note of my thread: THE 4164 IS NOT A DROP IN SOLUTION! You have to bridge pins, saw off others, and its not for the feint hearted. (On the other hand, since it eliminates the use of +12 and -5 in the memory circuits, it adds TONS of reliability and the memory chips don't get hot at all like the 4116's do. If you really want to make a project of this, this is what I'd do: 1. Just buy an eBay supplied Coleco power brick. 2. Carefully desolder (use a braid or desoldering iron) all of the 4116 chips and replace them with 16 pin sockets. You can then buy a truckload of 4116 chips and just drop them in, or tool up some modified 4164s as well. I hope it turns out well for you.
  10. Couple of things: -5 must be supplied "first" -- in fact, the Coleco wiring keeps -5 energized whenever the P/S is plugged whether the power switch is on or off. Its because of those damnable 4116 memory chips, which require power to be applied in a particular order. -5 and +12 polarize the substrate in those chips, and I fear that the absence of -5 will have caused immediate frying of the 4116 chips. Further, with your +12 so high, those chips didn't have a chance. Good news is there are only a few things on the entire board that take +12. First, of course, are the aforementioned 4116 chips. You can fix that. Do a search of my screen name and you'll find a post on how to replace them with 4164 chips (yes, wasteful as hell, but nice solution overall). Second, everything in the RF output box, most particularly the chip that converts the video signal and modulates it to RF operate on +12 volt. The caps in there are only rated to +16. You may have popped a few of those, and probably the chip as well. Beyond those two areas of the board, nothing else uses +12 The controller logic swings negative with the help of -5 voltage, but assuming yours was absent that won't be the killer. Conclusion: I'll bet you fried the 4116 chips and probably some stuff in the RF modulator. Good luck.
  11. NICE! I confess a good deal of the value in my package is the add in game, as Jungle Hunt and Do's Castle are both excellent games and somewhat scarce.
  12. BUMP, and start a clock: This ad closed and up on eBay tomorrow night if no one's interested. Thanks, Gonz.
  13. BUMP, and lets start the clock. If no one's interested in this one it goes on eBay tomorrow night. This really is a good deal. These go for $150 all day long on eBay without the composite mod and cartridge pack in. Or, make me an offer. Thanks.
