Re: Amstrad CPC Core

Because it use two ports for a total of 1024K extended RAM: &7Fxx and &7Exx.

Re: SHIFTER reimplementation on FPGA

Thank you to share your progress and let me know. :)

No sure if it is currently a project for me... I have to think about this Shifter replacement, but to do first my mainboard replacement because I don't want to hack too much my computer. And in this way, I will expect to understand it better.

Re: SHIFTER reimplementation on FPGA

Sure, I understand. Better to be set into the FPGA DPRAM in this case.
Thank you for your answers.

Re: SHIFTER reimplementation on FPGA

I spoke about an external DAC IC that embed the colour palette to save FPGA resource (used on PC VGA and A1200). Not to embed the palettes into the FPGA. ;) (sure, it is not good for a Shifter replacement part) By the way, do you know this FPGA : https://www.seeedstudio.com/Sipeed-TANG-PriMER-FPGA-D...

Re: SHIFTER reimplementation on FPGA

Yes, it should be a really good idea to offer a PCB to replace the standard part. (best with more features) I don't know if it is compatible, but an alternative should be to use a resistors network or a 3x Nbit DAC to input the digital pixels data and output the analog signal. Last but not least, it...

Re: SHIFTER reimplementation on FPGA

Sorry, probably my english is bad... I ask if the display can be done on a standard CRT monitor/TV set with 200 lines using your FPGA. Thank you for doing the test. I understand that result will be 160x200 for a 8MHz CPU (it remember the Amstrad CPC mode 0). If you are OK, I will be proud to use you...

Re: SHIFTER reimplementation on FPGA

Thank you for your fast answer. I spoke about the output line frequency to be able to continue to use the original monitors or TV set with 200 lines resolutions. Yes, it will require a 16MHz ST... I have found your topic because I was looking to redo a main board for my ST and though about using 2x ...

Re: SHIFTER reimplementation on FPGA

Really interresting topic and great work! :) I have seen your result on the HDMI display. Assuming it is scan doubled, Is the signal can be set to 15kHz too? About the screen mode, it should be really intessesting to have something like: - 320x200 8bit plan - 320x200 4bit plans dual playfield Do you...

Re: Daimakaimura (Ghouls 'n Ghosts) for the Atari STE

No news or answers since 6 months ago... Should we consider the project as dead? :?

Re: Daimakaimura (Ghouls 'n Ghosts) for the Atari STE

Hello!

Please, some news about the STE or the Falcon work in progress? :)

Thank you.

I wish all the best to this project in 2019. :wink:
