Re: Voodoo 2 4444SX

Next step is to implement part of the FBI<->RAMDAC communication (not video data) and clock generation in the FPGA. The FBIs need to read and write quite a couple of registers to configure the VIDCLK and MEMCLK. The FBI doesn't talk to the RAMDAC at all during system start-up, only when an …

Did some measurements and tests today, I enabled bitstream compression and increased the frequency a bit, the FPGA now finishes configuration 140ms before the PCI_RST signal is deasserted by the PCIe to PCI bridge. This is perfect, as the FPGA already does things while the Voodoo part is still in …

Quick because I really didn't do that much 😀 Already had the HDMI part working from this: https://sdz-mods.com/index.php/2020/06/22/voo … o-2-hdmi-board/ Just had to modify a few things to get it running on this board.

Thanks! Another small update, got video out: 20240108_222657.jpg It's internally generated in the FPGA, it's not video data from the FBIs. Now I need to measure default FBI video clock and FBI+TMU memory clocks on a regular voodoo 2 so I can configure some MMCMs and feed those clocks. After that it …

20240108_195011.jpg Today I resumed working on this, and did a minimal bring-up. Programmed the microcontroller that does the power sequencing, brought up the board and all power rails (11 or so) are OK. Also programmed the onboard FTDI IC that works as a JTAG for the Xilinx FPGA. I had to mess a …

Yes, searching for the FCC id seems to indicate the existence of "miroMAGIC 80SV Twin". No clue if this was actually released. http://www.mirosupport.de/fcc-id.html http://www.plasma-online.de/index.html?content=http%3A//www.plasma-online.de/english/identify/serial/cards/miro.html I find it really …

Thanks for trying, again! I tried searching in various ways, wayback machine and the Mamont FTP search thing, no luck, it doesn't seem to be on the internet. Maybe someone has the driver somewhere... one can hope. It would be a real shame to not get this card running and run some benchmarks, games, …

I can't seem to find any photos on the internet, so I'll upload some here: If I'm wrong and this is a different card, please let me know.

@analog_programmer That's one way to call it 😀) Don't worry, only a few of these cards will be made. @weedeewee I sure hope so, but it will need drivers.

@hard1k thank you! That was the idea, to push the V2 as far as it can go, while being able to use it in a modern system. @xelizor I won't be selling this, and I doubt anyone would want one, it's quite expensive to make one. I do plan to release the files after I get it working.
