I can produce more detail later, but first, some characteristics and advantages of what I'm proposing:

- x86 BIOS/OpenBoot/OpenFirmware code under BSD and GPL license
- kernel drivers under BSD and GPL license
- X11 module under MIT license
- flashable PROM so that boot code can be added for more platforms
- usable as the console on any platform that can take a PCI, AGP, or PCI-Express card
- downloadable schematic for the circuit board
- FPGA-based graphics engine so it's reprogrammable
- instructions on how to reprogram the FPGA, so it's hackable
- if we discontinue a product, we may release the Verilog code for the FPGA
- Since this is designed to be open-source-friendly, we want to play by the rules of the open-source community.
- Tech Source would actively participate in the development and maintenance of our own drivers.
- We will actually pay attention to problems and concerns raised by users and developers.
- We won't be control-freaks.



I haven't worked out a complete design spec for this product. The reason is that what we think people want and what people REALLY want may not be congruent. If you have a good idea for a piece of graphics hardware which you think would be beneficial to the free software community (and worth it for a company to produce), then Tech Source, as a graphics company, might be willing to sell it.



You might want to take a look at the onboard video market. Providing an open-source 2D rendering engine and the PCI glue logic that work on an FPGA would probably revolutionize embedded PC applicatiuons that rely on a graphical interface. Providing support to motherboard manufaturers who might want a low-cost onboard video solution (micro-ITX, etc) is another possibility.


Now, THIS is an excellent idea. If the volumes there would be high enough, it could be what justifies the project. We have had customers wanting embedded solutions, and through this project, we could provide them something even better in the future.


That would be your value-add there - provide the experience in video system design to the low-volume (<5000 unit) custom controller market. Smaller companies will not have the video experience to implement something like this. You could even bill the PCI cards as "developer tools". You'd just sell a lot of developer cards to *nix people...

You also might want to look at PC/104 and CompactPCI form factors - I think the industrial market will be a great target, and, after all, if you have to move 80% industrial equipment to justify the 20% AGP sales, it makes good sense. There might even be a market for ISA, SBus, and MCA cards, for people stuck supporting seriously old machines (386, 486, SPARC) where it's almost impossible to find working graphics cards. Even if it's a DOS machine, hardware is hardware, and a brand-new VL-bus card for someone's 486 would be pretty cool :)


This is a good idea too. I've already decided to try to fit it onto a 1/2 height, short PCI card (like the low-end 3ware cards) so that you can put the card into one of these compact cases.

At this time, I'm not sure it's worth it to do anything other than PCI, AGP, and PCIE, however. Of course, if someone comes along with a large enough order, we'd be plenty willing to do whatever customization they want.


I dunno. That's what market research weenies are paid to do - figure out if the market for a product is good enough to justify developement.

If this does work, though, moving the core graphics rendering engine to an ASIC would mean that a very small amount of work would be necessary to move the core to various bus architectures - even high-end PDA's and cell phones are going to need some serious graphics horespower soon, if the screens on them keep going like they are.

You also might want to consider marketing "developer kits" that include dead-tree documentation, boards, re-branded FPGA tools, and raw chips for those looking to do custom work on their own. I think it'd be fun to hack up an ISA graphics card on my own, even if mass production isn't feasible :)

It could be marketed to universities needing an undergraduate project in hardware design, too - for everything from video BIOS development to PCI interfacing to DAC implementation and physical board design. And the students wouldn't need to sign an NDA to get access to the cool new hardware...
