  1. Makary Brauner - Clubbed To Death (Rob Dougan) Fantastic!
  2. With the introduction of CF cards, the old XT-era 8-bit mode came back in the (P)ATA standard. Most IDE harddrives didn't support it any longer as it became optional when 16-bit ISA was mainstream, but for CF cards it is mandatory. In this mode, the full 512-bytes can be read through an 8-bit register. I'm fairly sure the Atari FAT32 loaders use this mode, too.
  3. You're not alone in this. I have it lying loose on the motherboard, but wrapped in foam
  4. emkay, have you compared your version with the adjusted version of irgendwer? I'm not talking about the sound of each instrument (which you call squealing, which is what my GF calls ALL the chiptune music I play around here ) but I mean how he transposed certain parts (or voices, or channels) so they sound in harmony? Note there's a difference between harmony and harmonics. Harmony, or lack thereof, is why others like or dislike your conversions. Harmonics, or partials (disharmonic overtones), is why you like or dislike certain instruments. Why don't you take Irgendwer's transposed RMT and apply your instrumentation? Let's see how that works out The point that's discussed here now, is the essence of why not more people like your conversions. I think most of us (I do!) appreciate the work you do on instruments. There are a lot of interesting sounds you are able to produce! But unless they play in harmony to eachother, it doesn't matter much that your instruments are better than others (less disharmonic overtones and/or interaction with other instruments due to pokey's nature). [edit: clarifications]
  5. http://atariage.com/forums/topic/258702-new-development-gtia-in-cpld/page-18?do=findComment&comment=3728309 Be sure to get this one and not the one I mentioned a post earlier, because that is the wrong one. Grrr, at first I ordered two of the wrong ones They come from the UK by the way.
  6. I've seen prototype new hardware running on an unmodified 800XL having no problems with divisor zero because they put schmitt-triggers on the serial and clock lines. It even went up to about 250kbps when externally clocked.
  7. Haha, yeah, I guess that happened when I increased the saturation
  8. Has anyone dumped the firmware yet? Mine says: ATARI 1027 A 0 83.8.5 It seems that by running the program/verify waveforms from an Arduino (for example) should be able to retrieve the data inside. NEC8749.pdf
  9. From the command line, I count colours with pnmcolormap: $ pngtopnm output.png | pnmcolormap 2 >/dev/null pnmcolormap: making histogram... pnmcolormap: 78 colors found pnmcolormap: choosing 2 colors... Basically, this is the first step of pnmquant and discarding the output, because I'm only interested in the number of colours found
  10. You can also take output.png from your conversion directory. Saves the trouble of creating a screenshot.
  11. Thanks! 11kHz is quite a feat already. Don't think there's much improvement possible there Even if one could get to 12 or 13 kHz, the difference would be negligible.
  12. Hi, Years ago, I created a MOD player for the Atari 8-bit (https://demozoo.org/productions/145663/). Considering my age and overall knowledge at the time, it wasn't bad. But, now that I'm more than twice as old (and wiser ) I think I can do a lot better. So, I was wondering, what is currently considered the best MOD player and at what frequency does it play the samples? What's the state-of-the-art player to beat? Thanks! Ivo
  13. http://www.ebay.com/itm/altera-Mini-Usb-Blaster-Cable-For-CPLD-FPGA-NIOS-JTAG-Altera-Programmer-/200943750380 Including shipping, it's actually cheaper than the micro match connector Does take 3-5 weeks to be delivered though. Yeah, hopefully Simius will release a few versions with different palettes. I don't mind the PAL palette (prefer it even), but I can imagine Americans want an NTSC palette because that's what they're used to.

  15. OK, let's be constructive This is the kind of tune that makes everybody run for the volume knob. The bass and the melody are in totally different keys! Now for the constructive part: I'm under the impression that a lot of the songs you post are MOD file conversions. Within MOD files, it is entirely possible that when a pattern says it's playing a C-4, it is actually playing a completely different note because the sample that is used for that instrument is not tuned to C but to some other note, let's say it's a D-4. Another channel/instrument that is tuned to a C note sample has to play a D-4 to sound in unison with the previous instrument. Now, you convert the patterns to RMT and it will play a C-4 and a D-4 note together instead of two D-4's as was intended by the original author of the MOD file. This will sound horrible. To fix that, you have to transpose all notes played by the first instrument by a full note up. You "vierkanal" song didn't have any problem BTW and hence sounded perfect.
  16. A feature that would be nice to have is small playfield width support. Gives you some extra cycles to change colours and placement of players, at the cost of a smaller image. The images I did before could possibly look even better.
  17. Perhaps you could optionally support the 128kB S/XEGS RAMCart . That way you can switch $4000-$7FFF and $8000-$BFFF, effectively bank switching 32kB. Or maybe we need a new RAM upgrade that can switch a full 48kB, including stack and page zero through an Axlon style bank switching location
  18. I have received the boards today! I'll start packaging tonight or tomorrow morning and expect to send them out late afternoon tomorrow.. Two people have not payed yet. Of one I'm fairly sure I'll get the money, but the other has not even read the two personal messages I sent, even after being online several times since I did. I'll wait another week or two and if I get no response I'll cancel the order(s) and have one or two more for sale and reserve one for you.
  19. Thanks! I also "breadboarded" the cable and tried all sync combinations and single sync lines, but I kept blanking connected all the time. Guess I could go back and try your suggestion, but I'm pretty content with my current setup, including audio on pin 1, too, which needs a separate connector (or even cable) on the 1084S. BTW I noticed that the Sophia PCB does not fit well in a fully socketed 800XL. It's at a bit of an angle because of the 74LS158 right above it. It only touches the IC housing though, so it doesn't make any shorts. If you add a precision socket to increase the height you can clear the '158, but then it touches the keyboard and the casing won't close properly. For now, I have it plugged in at a slight angle, but I'm thinking about removing the 158's socket.
  20. I got DB9-->SCART working on that Phillips CM8802 monitor. Great picture quality!
  21. Okay, fair enough. I have tried feeding the right signals on the right pins to the 1084S and the problem remains. It might be just my monitor though, so I'll move to my Phillips CM8802, which has a SCART connection. I'll keep you posted.
  22. I see. I went by what you said earlier: Guess I have to cut the cable then and rewire
