Another FPGA Gigatron implementation

As already stated on discord: there is somebody in Germany who made another FPGA implementation of the Gigatron, see https://www.youtube.com/watch?v=_SiCv_uo2bY What is nice, is that is uses the simple and cheap Tang Nano 9K FPGA board. I bought one of these boards for under €18 including shipping. ...

Re: Is this picture about instruction and operation right?

Re: Forum performance issues

The server is now running at the opposite side of the world from where it was! Performance is restored, there may be some last tweaks the coming period. Thanks again to at67 for taking over managing the forum.

Re: Forum performance issues

Thanks to at67, the server will probably move a bit earlier and from then on have improved performance. The move will happen somewhere in the next few weeks and will be announced here, as it will involve a short period in which new posts will not be possible.

Forum performance issues

You might encounter some difficulties with the forum site/main site. Especially when automated queries are made (bots) the current system is unable to cope with the amount of requests and will throw server errors.

Re: New Gigatron in Russia

The clock speed will not change the edge of the video, it will only make the Gigatron spit out the signal slower or faster. The more it deviates from 6.25MHz, the more trouble it will give the TV/monitor to sync to the image. But when sync fails, you will get nothing, not just part of the image. Whe...
