Hi there, I have started a Kickstarter project where I would like to create a tiny C64 emulator. Check it out and see if it is something you might be interested in https://www.kickstarter.com/projects/1524339386/worlds-smallest-c64-emulator?ref=nav_search Regards, StaringL

Glad you liket it. There is a chance that Sakura IT will do a batch of them (redesigned board) but not decided yet. In that case we will try and do an Atari version too. I will update this thread with information. Regards, StaringL

Hi again, I had some time over today so I fixed the last of the bugs. Seems Amiga has a pixel clock that is 14,18758Mhz, you learn something new every day... I think this is as good as it gets. It is hard filming an LCD screen and get decent quality through youtube, lets just say that it looks better in real life... https://youtu.be/nsnXf7O3oVg Regards, StaingL

Hi, I made another video as demonstration. I have fixed some bugs and also changed the output to 50Hz. I have also tried and highlight the current issues in this video. https://www.youtube.com/watch?v=dP0HOtBqJbk Regards, StaringL

Hi again ! I think I am done with the project Please feel free to check out the youtube link below. https://www.youtube.com/watch?v=rgNfMfjiVnY Be aware that this board has some state of the art, expensive as hell, parts. Lets see what the interest is in this gadget and go from there. Regards, StaringL

Thanks, it is working quite good at the moment. I have some problem with the position of the Amiga screen that I am struggling with atm. No particular reason for fpga choice. It seemd a bit cheaper overall, and fit this application very well indeed. It is soon ready, I will post more info here shortly.

Yes, j12 is 3.3v power out, there is another connector in the bottom that is 5v input. Actually, vga is not the point with this device. You will get 720p hdmi out, so i did not thought vga with scan doubler important. If it's needed a simple device can be hooked up between j14 and j16 to do the scan double. To be honest I do not have a lot of knowledge about this. Regards, StaringL

Yes, you are right, actually all signals (r, g, b, vs, hs) are available on J16 by default. I have used the VGA connector as test purpose (input), but I guess it can be used as output as well. I did not try this though, since I do not have a monitor that is compatible with 15Khz. Regards, StaringL

Hi There, I have just developed a converter for the Amiga computer. This way you can connect your Amiga to a modern monitor or TV without having to use that annoying composite / tv interface. It's not done yet, as you can see, but I am pretty far along the project. Have a look . I will update this thread when I have updates. Regards, StaringL

I took a quick peek at the hardware and CPU used. I was rather surprised to see that the CPU is clocked rather high at over 3 Mhz. I was also surprised to see that the Zilog Z80 is still selling today (although the code written for the original ColecoVision would not work I guess). It would be a fun project but honestly, I must say that my strength is (at least for the moment) totally drained with my previous project. If anyone else is up for the job I would be happy to help with questions or any type of lightweight support.

This is really cool stuff, as I mentioned in another thread Joysticks could be implemented as well to really seal the deal

Haha, that is absolutely beautiful I like it! Must have been really difficult with the keyboard array. I would miss the joystick though. Raspberry-Pi does however have a few GPIO pins. These could together with some modification to the VICE code be used as Joystick input

The hardware and software that I made was just a silly personal project that I had. I always wanted to make a C64 emulator but never got around to do one until now. I'm not sure but I guess for the project Pixelboy suggests (with emulated sound) it is possible to buy a Raspberry-Pi board (~50$) and put a ColecoVision linux emulator on that board (there should exist a few already?). I think Raspberry-Pi supports anything that is needed. It is also the exact same form factor as the board I made. I would love to try this myself but now with a baby and all, I have limited time and fixed schedule

The content in flash is updated using UART port. The maximum transfer rate for MCU is 5250000 baud. No problem mate

Thanks for all kind words . I'm happy to see fellow nerds still cheering for the old C64, warms my heart. I never did own a ColecoVision * That things pretty sweet how much does something like that cost? I'm not sure but I would not be surprised if I spent around 1000$ for the whole thing including prototyping stuff. Six layer custom board does not come cheap when produced in such low quantities Just the board with components (no tooling costs from fab included) would set you back around 50$. The display is around the same price. * I assume that you can load C64 software via the micro-USB port? No, this is not possible. The micro usb just provides the power. But I have 4 Gbyte of flash that I can load with whatever I would like to run. Today I store about 30k games there (including the roms for the C64 ofc). * I also suppose that you can plug a standard PC keyboard via the micro-USB port, so you don't have to mess around with the touch-screen too much? I'm sorry to say that this is not possible, I need to fiddle around with the touch screen . When it comes to throwing a grenade in Commando, it kinda sucks I agree (the touch keyboard does however work even though you don't see it).. If I would like to have support for keyboard I need to use the UART port. * If you were to do something similar with the ColecoVision, I would build a shrine in my living room to worship you. That sounds fabulous .There is actually no restrictions in the hardware to just be a C64. It could become a ColecoVision as well (SID6581 sound chip that was used in C64 needs to be switched to SN76489 though) * Can you set the display to not be stretched? Yes, that would not be any problem, but it is not implemented in current version. One line needs to be changed in the code to get original screen. I have learned to like the wide screen actually...

Hi All, Wanted to share with you my latest project. I have made an emulator from scratch and put it on a custom made board. I know you will like it Youtube Link Regards, StaringL
