  1. What about HDMI output too?
  2. Would this v9938.vhd file be useful for a maybe future "F19A"? v9938.vhd.txt
  3. Do it! Any other with nice animation? It could be another inspiration for an A8 demo Another Bad Apple version...
  4. This isn't trolling, I just want to understand. I see the C64 versions feature the voice... What about this Atari 5200 version? And this Atari 8bit?
  5. It seems a nice machine, but I suspect it may be expensive to buy and need to place it inside a ti99/4a console. I hope that FPGA implementation resurrects someday and someone be able to port it to MiST
  6. What EDA software have you used? Do you plan to release the design files on a place such as GitHub? It would be interesting for people into electronics, even modifying it to "break" the 1983 rule (replacing memory chips with higher density ones, using CPLD or FPGA, integrate updates, convert it into a Geneva, etc).
  7. I can't help you much. I found two Apple IIGS emulators still in development https://github.com/jmthompson/xgs https://github.com/digarok/gsplus(based on KEGS)
  8. I see a hub and a MultiJoy16, but nobody want to release the schematics to spread this hardware. Why?
  9. I see. I didn't know ysung two MultiJoy8 equals a MultiJoy16. But where are the schenatics of MultyJoy16 that uses the 74154 Whewe aew they
  10. What about putting Real Mechanical Key-switches? This could make the A8 compies to suck even less possible, despite something like that would seem impossible
  11. Sorry to write in an old topic. Where's the Multijoy16 schematic? I can't locate it. I just found this. There's some references, but I don't understand German http://www.abbuc.de/community/forum/viewtopic.php?f=15&t=2320 http://www.abbuc.de/community/forum/viewtopic.php?f=15&t=7793&start=0 http://atari.sk/satantronic/MultiJoy/index.htm No schematic, "coming soon" http://www.abbuc.de:80/~hardwaredoc/projekte/hardware/ultrajoy-pro/ultrajoy-pro.html Some references... http://atariage.com/forums/topic/219776-network-multiplayer-atari-games/ http://atariage.com/forums/topic/223879-atari-8-player-multijoy-adaptor-new-full-color-assembly-instructions/ I see there's a 74154...
  12. Any news? It would be amazing to have a multijoy8/multijoy16 with sega genesis 6 button controller support, but I suppose that would be too complex to do...
  13. Are you planning to share your design files? I wonder why you designed Multijoy8 instead MultiJoy16. Anyway, I'm interested in a PCB as it's just 8EUR.
  14. Is Antonia still available? I plan to save money to put it in a 600XL or 800XL. It might take two months, as I'm broke. I also wonder if the 65816 can run at higher freqs like 14MHz or 20MHz. What about SDX?
  15. It's Carmen Sandiego. Carmen Santiago is the character of a "parody" game that teaches Dante's "Inferno". https://en.wikipedia.org/wiki/Carmen_Sandiego_(video_game_series)#Where_in_Hell_is_Carmen_Santiago.3F
  16. Any hopes about this? Maybe he can release the code at least...
  17. I see the schematics aren't complete, not all KiCad project files are available :/
  18. I just wonder how TI-99/4A / Geneve and such are emulated in MESS compared to other emulators. Is new hardware like F18A supported? And I also wonder why standalone emulators are still successful. I also see MAME/MESS (do we call it MESS or MAME now? Since the both got merged and it's just a matter of compiling options) to be messy to use for the average user. I hope the new Lua GUI improves at this.
  19. Yes, everythiing got really interesting. I'm amazed how the TI99 scene manages to do great things. I tried to get one many years ago, but there were some problems and these weren't shipped to me (long story). This device would manage to add true VGA output to many retro systems. And if you someday get motivated to it, please consider add support for successors of the 9918A VDP. But it would be even better if you make a team behind this project to make it growing Someone experimented with SMS VDP on TI99 - There's Sega Master System VHDL code with VDP implementation. This is what I found in the Playsoniq user manual: - The Memotech MTX range of home computers is lesser known, but those features a Z80 microprocessor, a TMS9929 video chip (same as the MSX1 video chip except different color encoding output) and also the same audio processor as used in the Sega and ColecoVision. And Franky user manual Graphics: VDP (Video Display Processor) derived from Texas Instruments TMS9918 - 32 simultaneous colors available (two separate palettes with 16 colors out of 64) - Screen resolutions 256×192 and 256×224. PAL also supports 256×240 - 3.546893 MHz for PAL/B/G (through 4-pin DIP crystal oscillator) - 3.579545 MHz for NTSC (clock provided by MSX) - 3.575611 MHz for PAL-M (by replacing the 4-pin DIP oscillator, not included) - 8×8 pixel characters, max 463 - 8×8 or 8×16 pixel sprites, max 64 - Horizontal, vertical, and partial screen scrolling "The Sega VDP is for a large part TMS9919 compatible." Misc info... Texas Instruments' TMS9918A was succeeded by Yamaha's Yamaha V9938, which added additional bitmap modes, more colorful sprites, a vertical scroll register and a customizable palette. The V9938 was used in a third-party upgrade to the TI-99/4A — the Geneve 9640 'computer-on-a-card'. The V9938, in turn, was succeeded by the Yamaha V9958, which added some additional high-color modes and a horizontal scroll register. These chips were used in the "TIM" upgrade card for the TI-99/4A, as well as on the MSX 2 and MSX 2+/turboR systems, although rumor has it that the V9958 was also used in a generation of the Photo Play arcades. Yamaha also produced a Yamaha V9990, which is considered the follow-up of the V9958 by some, but it is not backwards compatible. A graphic chip extension utilizing the V9990 exists for the MSX in the form of the 'Graphics9000' cartridge by Sunrise.
  20. Hello. Thanks for your efforts! Your VDP replacement is useful for many platforms. Are you going to publicly release the 9900 and the VDP cores?. Do you yhink it may be useful for other ptojects? Kind regards, 1. Digilent Spartan 3E Starter (this is the board the F18A was initially developed on: http://store.digilentinc.com/spartan-3e-starter-board-limited-time/Digilent makes good stuff and they have all kinds of boards in many ranges, lots of I/O boards, etc. 2. Of course the Gadget Factory: http://store.gadgetfactory.net/ The Papilio boards are nice and there are a lot of add-on boards for I/O and such. 3. Xess.com: http://www.xess.com/ 1. The F18A uses a Spartan 3E 250K, which is a little smaller and a Spartan 6 LX9. The whole F18A design *without* the GPU was under 50% utilization of the FPGAs resources. After adding all the other features like the GPU, stack instructions, DMA, etc. the utilization is about 96% of the FPGA. 3. A complete 99/4A SoC with F18A could fit in the 3E-500K or LX16. Have you considered to port it to the MiST board? It has tons of cores ported already https://github.com/mist-devel/mist-board/wiki/GettingStarted
  21. Are there guides and communities to make non-TI99 users program for F18A?
  22. Amazing project! I didn''t know. I have readed all 33 pages of the forum thread! Any hopes your "cores" could be available for a full FPGA implementation for systems like MiST? Are you considering to eventually release it as Open Hardware?
  23. Did you develop it using some Version Control System ike CVS, SVN or Git? Are you willing to publish the source code?
  24. I'm just a stalker here, but I would like to reply about your message. Why do you use this kind of response? Why are you so much strong opinionated? If you have something against the author or the way of making software, then keep use the software you prefer or make your own (I cannot find one in atari8.co.uk). Why do you write in that redundant and literary-like way? I appreciate your skills at the English language, something it's quite difficult to me as I'm not native English and my formal education was quite crappy, but I don't understand why the same message can't be written in a simpler form. It seems you feel upset about someone saying your software was buggy, because you're too proud on it. Why people can't fail? And if the current AspeQt developer failed in the way of dealing the problem, he can now understand his wrong ways. People can learn from it's errors. Personally, I would prefer a more universal program like AspeQt but for 8/16bit systems (both consoles and computers). I was an uCON64 user in the past and had a MDPRO from ToToTeK, I miss that kind of software integration. But I consider AspeQt quite useful, despite I'm more of a keyboard junkie (so I would prefer a ncurses frontend). But this doesn't make me to hate AspeQt or not wanting to use it.
  25. So... Are there some volunteer to help with AspeQt development? It seems there is need of some help and form a small team at least.
