Re: Process video with HW, not SW(ROM)

Hi 1kb, That's an interesting idea/approach. Thanks for sharing. The total transistor count for the whole system will go up quite a bit, making the hardware more complicated. But you will gain speed and a more friendly system from the software viewpoint. It would be interesting to see if this is fea...

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. ...

Marcel would have enjoyed having MSCP running there.

I've removed it for now. https://gigatron.io/emu/ is working again, and so are https://gigatron.io/emu-12.5/ https://gigatron.io/emu-dev/ https://gigatron.io/emu-dev7/ https://gigatron.io/emu-invader/ https://gigatron.io/emu-pucmon/ https://gigatr...

Re: Is this picture about instruction and operation right?

Interesting.. you found an error in my slides, after >5 years :-) The slides are indeed incorrect. The correct information is on GitHub: https://github.com/kervinck/gigatron-rom/blob/master/Docs/Native-instructions.pdf . In my slide, the instruction matches this order: IR1 IR0 IR4 IR3 IR2 IR7 IR6 IR...

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.

Re: Forum performance issues

I made some changes (throttling requests), hope that'll make it better. Coming July, the server will move.

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.
