  1. Its' the only thing plugged in. It works fine with my other 130xe.

     

     

    did you get this all sorted out?

     

    chrominance may be missing.

     

    some times there is a switch or a person disables it entirely for hi res no artifact display. I never like the remove the whole circuit or box approach for that reason.

     

    I would touch up the solder joints making sure to clean as well adjust the potentiometer and then verify nothing is missing or any traces cut/broken.

     

    After that I might start checking the driver circuit (just a few transistors and caps) Taking care not to forget to clean the rf modulater channel switch while I was in there.


  2. Hello

     

    I need music from DEFENDER OF THE CROWN, in PC Dos version are 4 songs, and I need them in .CMC format. For next is there any convert program to CMC music?

     

    Thx.

    !!!PC VERSION!!!

     

     

    HERESY!

     

     

    Take it from the Amiga version... the real version, not the PC port!

     

    You should have no problem loading it into the Amiga Emulators: UAE or WinUAE.

     

     

    ST version of this as well, get all of them and take the best parts


  3. What's really going to get ya is after you adjust the tint pot, art pot, chroma pot. Is that maybe I am really seeing purple and your seeing blue but we all have been taught it's pink! Who could really know? I mean it could be tasty wheat or chicken for all we know.... it's the matrix if you star at it long enough....

  4. I beg to differ, there is a correct artifact... see the flag is red white and blue. and well correct artifacting makes it look like the USA flag. And also drol as well as jingle disk look scary on the machines that have the wrong artifact cap. The cap in question is c53 on an xl. I have performed this mod on 3 different machines and the whole family and friends cheered when jingldisk looked like it was suppose to at Christmas. Some people say the whole point is to remove artifacting... I say the point is to have artifacting when the program calls for it on purpose and to not have it when it does't. Add a Handy little switch for that. Ultima fans know what I mean, it meant so much that Lord British included a calibration step at games first running to pick what colors you saw. then it adjusted them accordingly. c53 was treated to whatever the had laying around at certain times and caused this. The video section resistors and caps all got the 'close enough' treatment from the manufacturers. Testing and acceptance should have included artifact and chroma luma mode verification. Then at least 90 percent of us would not be opening our Atari to pull signal that already exists and should be connected and Or dealing with fixing pink trees and blue fireplaces.

     

    use a variable cap or something near 95nf to 100nf piggybacked at c53. I think that was the value but all the techs here should be able to test this and give you their precise values. I think mine was 97 but your mileage may vary.


  5. Interesting, I remember my pal Jeff had a commodore and we compared this game side by side as well as flight simulator. Griddrunner won on the Atari but Flight sim was a toss up. The Atari loaded flight sim faster. And gridrunner was instant as it was a cartridge.

     

    Am I understand it the game will be made better graphically and enhance the gameplay features adding some new ways to blast things from the grid?

     

    Mintner has his Atari version posted for download at his sight, you might want to check that out

  6. Not to put to fine a point on things but everyone said you could not have digitized sound at the same time screens moved with objects and game play, this was believed by everyone, in fact when I once mentioned such a thing everyone came down on me hard....

    I no longer had the proof.... and you know what Sheddy proved I was correct with Space Harrier. And then that was used for tempest! Because He taught himself and had re-learned on his own a forgotten thing. Whatever makes it possible. I like the ideas the programmers/coders are presenting. The artwork may not work in the end but at least they can be converted or used as an experience to build on. Having been a beta player tester for so long I have seen many things that never came to be. Canned by people who did not like what they were seeing and the incredible routines driving the game were lost forever when it could have been used to help other endeavors. btw the a8 was indeed used heavily in tron for sound. Who has the software? Lost! No one has it.... who knows it might turn up one day. Or like in example of Space Harrier someone may rediscover the tricks to do it and we will be blown away again. So I say keep drawing in all the different format you can find, as the coders here have already started thinking about how to handle the game mechanics, logic and tricks to get around issues... I think it is inspiring to see another person working hard on the idea as well as getting others to think about how it could be done.

    I would like to express my personal thank you to the guys discussing how to get the ninja to move without being decapitated, it those kinds of suggestion and thinking that make stuff happen!

  7. I was pondering on the bus today: probably a very simple and useful upgrade would be some banked RAM (maybe 4 x 16K banks) accessible by ANTIC/CPU but controlled by a register other than PORTB. This would have all the advantages of VBXE's ANTIC banked mode for applications aware of it, but without the rest of the features. Any RAM-hungry graphics application would benefit from keeping the DLs and screen data outside main memory.


  8. Well,

    is there already a fix for "Bandits" available, so it loads on the XL/XE computers without the translator disk ?!? And how about the "Tail of Beta Lyrae" ?!? -Andreas.

     

     

    one of the first games I played on my 800xl was the tail of beta lyrae, why would you need a translator disk for that? It alread played on the XL right out of the package


  9. And another delightful surprise: I was leaving some bulk feedback for recent purchases and was prompted to leave feedback for gingreen1, the seller who dropped the 65XE out of the loft hatch, smashed it to pieces, then relisted it in perfect condition a week later. Didn't expect to get the chance to leave feedback, because I cancelled the transaction. Ah, what glee! icon_mrgreen.gif

     

     

    this is what ebay has been like for about 2 years...

     

    I have just returned from the dismal task of shutting down facilities within our region and found the archiving company took items for shipment and stored them instead! At just over a year and some months.

     

    And Yes that means a lot of jobs just got flushed this year! I mean a good number of people are now doing whatever they can to make a buck, that being said, the few I have spoke to sold stuff on ebay and were grateful for anything they sold at any price and honored their transactions.

     

    If people in dire straights can be honorable, someone just clearing out their loft has no excuse.... period.

    Suzanne is detestable. BTW she has the same name and style of a suzanne that screwed me for the lantronix adaptors I needed for putting BBS back online to internet. ebay has gone to the stray rabid dogs


  10. It's not useless.. You use base ram for screen memory, and write your CPU code to run from 16k banks.. Leave ANTIC alwayse pointed to BASE RAM. Then put a service routine somewhere above $7FFF that brings the CPU into main ram, does whatever manipulation you need to screen data, and then returns the CPU to whatever extended bank was selected..

     

    This allows you to have almost 30k just for screen data if you want it, as many 16k banks as you need for your CPU code.. And you don't have to run anything in the VBI interval..

     

    Separate Antic/CPU access is one of the kewlest things atari EVER did.. and to delete this feature in favor of a single aditional bit of extended ram adressing is completely ASSANINE.. Take the useless self-test bit instead.. Or better yet, just build a small circuit to decode an entire additional 8-bit register in the PIA shadowed adress space.. Then you can go up to 16megs without changing ANY of the stock 130xe PORTB bit assignments..Your machine will remain 100% 130XE compatable, and have the ability to use 1024 16k banks for software that "knows" about the extra register..

     

     

    AMEN Brother! and an old school w00t!

     

    That squarely said it debate over!


  11. I really hope the xep driver gets finished, the original wastes so many cycles doing nothing, the modified pal version nisselroy posted was fast putting all the parts together and playing nice with X would be the trick, ntsc pal removed waits and the extra modes. It still would be nice to do the both screens at once trick we saw with bobterm, one screen was the terminal and the other was the menus both at the same time.

     

    Yes I know...two monitors connected to the eight bit but hey, I kept one for 80 col bw and the other for color so.....

    Did anyone finish the color mod for the XEP?, it pretty much has what it needs already just some bits needed to be put back in....

  12. Cool stuff, the manual could be a help. I am putting this one next to the ballistics calculation disk!

    Going through some of my stuff tonight and I found this APX BASIC language program to help people choose hydraulic cylinders, pumps, and motors. I sort of doubt anyone will need this, but since I have never seen it anywhere before I figured I would share it. I have the original manual if anyone decides they want me to make a copy.

  13. Just curious, is there anything on side 2 of that disk, I could be mistaken but there are possibly 3 sides or disks for this device.

     

    I apparently have a disk for the Alien Voice Box II speech synthesizer called the VOICE BOX II - ATARI - SPEAKING, SPELLING, AND SINGING © 1983 THE ALIEN GROUP.

     

    I have no idea why I have this because I never owned such a beast. If anyone has one and needs this disk here it is!

  14. Most of these games would make good MAXFLASH conversions then everyone could enjoy them!

    Just played a hole on the emulator; nice work for the 2nd new game of 2009!? Is there a way to transfer .CAR (or .ROM for that matter) files down to a 1050 disk to play on a real Atari, or, do I need to wait for an executable/file version :?:

     

    Well, file version is possible (for 256 kB machines). May be I'll convert the game into file version in the future but right now I'm pretty flooded with another A8 projects...

     

    Try to contact Lance of Video61 if you want to play the game on real HW. May be he could produce some carts with boosted version...

     

    F.

    I've only got a stock 130XE / 128K, never mind :| Great work though.


  15. DOCTOR ROTCOD or doctor doctor, did you get the the rom or is it no longer needed?

    FYI i've tried burning the ROM to a NEC, Fujitsu, Seeq, and AMD with no success. Does anyone here have a spare ROM that works they would be willing to sell me? This is the only thing holding me up relaunching my BBS. Thanks in advance.

  16. I never found a copy of this that acted 100% like the store bought one I had..... would be interested in recreating it from VAPI but do not have the VAPI tool to do it...

     

    That's a point worth considering.

     

    There's also the chance they took the opportunity to revise the copy protection as well... then again, maybe only some of the subsequent program/data not present on the first disk was changed.


  17. I have purchased two sio2sd units but it looks like the sdrive nuxx might have been a better choice.

    the support your providing far exceeds what I appears in the sio2sd world!

     

    It's not feedback really. It can be turned off, I'd have to look up the necessary poke. It is possibly more annoying since the SDrive doesn't need to seek or wait for the sector to be ready, so the gap between sectors is very small. Using the higher speed modes, it becomes like a solid tone.

    Oh, I apologize. I didn't know that. I thought it it was something unintentional, considered acceptable noise in the design.

     

    No, not at all. I'm beyond happy with the Nuxx and it's performance! I wish there were more people that would make complete package projects like this.

     

    My only complaint was more from a general Atari use standpoint. I'm coming from a different world of classic computing and don't have the same level of nostalgia as some do for the beeping on drive access. I understand why it's there, but would kill to turn it off just due to it driving me nuts to listen to it. Nothing at all to do with the Nuxx! In fact, the Nuxx makes it better since it loads the programs so much quicker and I don't have to listen to it as long!


  18. 1.2k should have been brown red red

    This is for the XE computers.

    It is best not to rub the mylar's traces, that oxidation protects what is left of the traces, if you clean them all it exposes fresh

    materials to oxidize causing the whole thing to repeat. As was evidenced, new old stock mylar did not correct the problem.

     

    The amount of resistance to decrease in this case looks to be quite minimal as the keys are at the borderline.

     

    A target combination equal to 220 ohm should be safe.

    Do not disturb the 47k resistor (yellowvioletorange) or the diode above it.

     

    1.2k ohm (brownredred) in parallel with the existing 270 ohm resistor should get you down to 220 ohms.

    1.1k and you get 216. You can nudge it down to 1k and get 212 and so on. only use what gets the job done...

     

    if you cleaned the mylar off go one step below what first gets the keyboard working, that will ensure that it keeps working

    after the next round of oxidation is complete.

     

    There you have it.

     

    some formulas for calculating resistance in parallel are

    Combined resistance of two resistors in parallel:
      	R=[u]R1×R2[/u]
             R1+R2
    For more than two resistors connected in parallel a more difficult equation must be used.
    Add up the reciprocal(one-over) of each resistance to give the reciprocal of the combined resistance
    Rtotal:[u]
    [/u] [u]1[/u] = 	 [u]1 + 1 + 1 + [/u]...
    R 	 R1  R2  R3  ...
    The simpler equation for two resistors in parallel is much easier to use! 


  19. I give this an old school w00t! It seems to be working pretty darn well, I hope you post it on Atarimax site as well. this thing flys

     

    The final version of the patch is coming closer, I've uploaded the (hopefully last) preview version to my website:

     

    http://www.horus.com/~hias/tmp/hipatch-090503.zip

     

    New in this version:

     

    - press SHIFT+RESET to do a coldstart

    - faster checks when determining the highspeed mode (speedup when accessing a stock or non-existant drive for the first time)

    - Pokey divisor 0 (126kbit/sec) works stable with the NMI patch

    - Pokey divisor 1 (110kbit/sec) works stable with the new fastVBI code

     

    so long,

     

    Hias


  20. Low interest? I have been reading the whole time... I just think me typing wow this looks cool along with 50 other people would not be very productive....

    lurking is what we're doing. take it all the way please!

    I am hungry for something other than the 3 atari vs com vs atari vs com vs atari... threads. or the mixture thereof. I am glad someone is doing Atari related posts and related works as this is suppose to be AtariAge! Let's clean out the versus threads like you know we want to clean the house and senate, throw the bums out! I'm with Claus! Onward with Atari projects!

    It looks like you use nothing but careful programming to sync the video.
    Not really. It is synced merely because the SRAM sees the same address that ANTIC puts out for its video, except for the one bank bit. The AA rainbow picture above was drawn by a simple BASIC A+ program with a few pokes to manage the banks, the display list, and the OS bitmap pointer.
    The diode just clamps the LUMA?
    The diode, in series with a resistor, sums the LSTTL output into the composite video signal. The diode allows a high output to increase the luma level but prevents a low output from decreasing the GTIA luma. Kind of like an open-collector output but inverted.
    What's next?
    Due to the low interest here lately, I think I'll just finish Stage I with the 80-pixel, 16-level mode. Combined with the GTIA 16-hue mode, it will display 256 colors without flicker. If that does not rekindle the excitement, then I'm done.

     


  21. never been able to get ibm tetris to work on ntsc machine, the name is a misnomer anyway since it is the spectrum holobyte version that was a copy of the original Atari version that stupid Judges in the US made Atari yank and recover then destroy due to the whole licensing only to like minded government fiasco/ ussr to nintendo..... never should have happened since the Atari is indeed a computer complete with monitor and keyboard. But hey..... maybe some talented crew will restore what was lost. Since the Atari version of the game is still in the record books as having been the "best" version. Look it up. LOL the best version that never was allowed to the home user base at large. One can only hope to see it faithfully reproduced on the 8 bit Atari. I wonder if any escaped destruction? They must have given the track record of stuff turning up... one day.... one day...

    Well,

    how about the following Tetris clones:

     

    - Warsaw Tetris (available as a bootdisk, a 16k and a 32k fileversion)

    - Ultra Tetris

    - Lunacy Tetris (lets you playback Pokey Player tunes while playing)

    - Chromatics

    - Getris

    - Blockaboo

    - IBM Tetris (with very nice picture backgrounds!)

    - Atatris and Atatris 2

    - Tetrix

    - The Wall (by Itay Chamiel in RGB-15 mode)

    - Speed Puzzler (from german Atari magazine)

    - Flowers

    - Fortress

    - Hot Blocks

    - Tetris (one version by S. Brabec, one by HMC)

    - and many many more...

     

    Still, I love tetris games with the standard tetris blocks, I don`t like enhancements, where blocks e.g. look like a + or other crazy forms, alas, there are quite many tetris versions on the A8 which have non-standard blocks...

     

    So, I would still be interested to see a new Tetris version, even in Gr. 10, if its a good one... Attached IBM-Tetris (requires XL/XE, Basic off), since it seems not to be very well known by now... all the rest can be found via atarimania.com -Andreas Koch.


  22. I once had the full pacman version that had all the intermissions (cartoons) exactly like the arcade in disk format... the only version I can find of it these days is a cassette image.... So guess what I do to play PacMan as it was intended? Yep, it loads while I make a sandwich and get a beverage. As the time left to load counter ticks on! Many cassette version actually had more screens and better software versions than the crappy cartridge or disk versions. Took forever but was well worth the wait! Who knows what lurks on some of these ignored gems floating around out there?

    Why go back to floppies when you have IDE and SD card interfaces available?

    1-To back up/archive some stuff that is not on the Atarimania site

    2-Nostalgia, I actually like the experience of using all the original hardware,the sounds, the waiting, the wondering if it is going to load. I even like to load a cassette game every now and then :twisted:

     

    I'm not "going back" to floppies, just using them alongside the newer alternatives

     

    Ditto :)
