I just thought of something that would be interesting...

Voodoo2 on an FPGA on a mini PCI card for late 90s early 00s laptops. Though either internally cobbling to VESA pins or whatever you'd need to do to get it on the LCD might be a pain. Otherwise I guess it's awkward ribbon cable to VGA out for monitor only.

If it did it over PCI completely like a PowerVR or MPEG card that would be easier. Power VR cards aren't super complex, wonder what the chip situation is like, hmmm.

Sounds reasonable!

There once was at least one V2 for iMac Mezzanine slot, too, so a compact size per se seems doable.

The PowerVR for Mini PCIe would be interesting, too.
I remember that their had been h.264 decoders for netbooks once.
Were based on a Broadcom chip, I think. Habey HB-VD920 etc.

It's a good idea, but many laptops from the late 90's & early 00's have good 3D cards already.

I would dispute the good 3D and that there are still many, there's dozens and dozens with chipset graphics, rage mobilities and S3 stuff, for every one that had Geforce or Radeon, until a few years into the noughts. 2003 or so the proportion with better graphics rose somewhat. Having been a laptop shopper in that timeframe when they were new, it was hard to find one with decent graphics then, sure, the magazines reviewed them, finding them for sale was another matter. I never ordered direct from Alienware or anything like that though, so I wasn't looking at $3000+ machines. Then there was the "forgot how to make hinges" "bad caps" "lead free solder" agents of slaughter which took these things out at a massively high rate. So apart from getting real lucky or spending a fortune on eBay after searching for months, you're not likely to get your hands on one now.

Dos capable sound went away just as the higher proportion of late retro compatible graphics kicked in, or the Turion/Sempron models that survived solder problems would be nice with X200/X300 onboard, which are basically Radeon 9600s. By then, screens were wide too.

Anyway, repro Voodoos are selling for desktops that could have any other card plugged into them, so I don't think the existence of other options is a factor. PowerVR doesn't have quite so much of a following though, but seems way easier to do. It's more of a tinker/novelty option rather than the be all and end all of late 90s 3D.

PowerVR certainly looks compact enough

My first gaming laptop was from early 2006. It was based on a Clevo M570A chassis. I believe it had an nVidia Geforce Go 7800 GTX and Pentium M CPU. It played all the latest games at high settings.

I dont recall their being any worthwhile gaming laptops much before that. But maybe I am wrong.

I have a Dell D600 from around 2003 with Radeon Mobility 9000. It struggles with games from 2001 onwards really.

While the datasheet is in Japanese, the pin out and supported memory configuration pages are really in English (obviously), so at least that clears obstacle to designing the PCB.
That being said, is there still NOS inventory of the NEC made PowerVR somewhere in the world?
I assume the demand for this chip dried up by 1999, and remember Matrox fire selling their m3D card with this chip over at CompUSA back then ($30 after a mail-in rebate type of a deal).
On an unrelated topic, I have purchased several NOS copies of S3 Savage4 Pro recently.
I will eventually like to manufacture PCI and AGP version graphics cards eventually.
It is definitely a better chip than ATI Rage XL.

With a superficial search I found a couple of places with 4 figure inventory numbers, but I have not reached out to confirm. It would be easier if some turned up on eBay or somewhere, to get a few to mess with. Yeah I saw the pin labelling but assumed there might be some important notes in the text. Though I am not super sure that's a "real" datasheet, since there is not enough packaging and timing info on it.

Right, 1999 or so they were super cheap on a card, I got an Apocalypse 3Dx for $12 from Compgeeks back then, kinda wish I had grabbed a dozen now.

Anyway, still gotta confirm the chip would fit in MiniPCI card dimensions... and it would be a fat boy with PVR on one side, DRAM and crystal on the back and whatever most essential discretes crammed in.

Next guess, 32 bit PCCard for type III slot only maybe.

Those would be cool, I'm a couple dozen projects away from needing a second Savage though.

It does not appear that the very short Japanese language datasheet (14 or so pages) contains anything other than its chip pin out and general memory configuration.
Since this version of NEC PowerVR does not contain a VGA graphics core, one does not need a VGA BIOS ROM.
This makes the ROM copyright issue a non-issue for a "gonzo" retro graphics card.
I guess the chip used in VideoLogic Neon 250 is not really available (they probably weren't produced in numbers), and this one requires far more of design support to make a graphics card.

S3 Savage4 happened to have excellent hardware and register programming documentation on the Internet, and the only missing is a customer reference schematic.
This is why I decided to purchase several of them recently.
