Does anybody remember this card?

IBM was working with Video Loca (later bought by Bitboys) to produce a video card that could run the XXXGA resolution at 4096x3072 at 42bit color depth at 69Hz, (2D > 3D), they were used briefly on CIA's IBM PS/2 Model 420 workstations that were responsible for scanning the American aerospace for early detection of foreign attacks, until they were decommissioned in August 2001.

I remember that this card had five GPUs on it, much like their later work with the Bitchin' Fast! 3D. And I remember thinking to myself that Matrox was the only manufacturer to make GPU for both the 2D and the 3D cards (I can't even remember the specific gpu used). I'm trying to put together a computer with 5 separate cards that has similar or same gpu core as the one used on the Bitchin' Fast! 2D, and I was wondering if anyone here could remember what the other four GPU's were.

Many thanks.

I only forget.

Bitchin' Fast! 3D was literally a joke ad.

There would have been absolutely 0 reason to have 5 different 2d cores on a single card.

On top of that, what would 42bit color depth be good for anyway? No displays would have even been able to use that.

The biggest hurdle back then would have been the amount of video RAM needed.

This info is absolutely incorrect for displays.

I must be some kind of standard: the anonymous gangbanger of the 21st century.

What do you mean? I linked it because that is the amount of video needed for uncompressed frames at listed resolutions and color depth.

bpp is not the same as bpc

You also need to include alpha channel. Which is, obviously, not a problem for uncompressed video frames.

Ok, true. So what would the size be at 4096x3072 at different bpc including alpha channel?

Actually, with analog signal, every display is able to use that.

Yeah... Use it as in it would physically work.. but how many colors can the monitor actually display?
Most of the better ones later on were sold as supporting 16.7 million colors if memory serves.

The number of colors available for any X-bit image is just 2^X if X refers to the bits per pixel and 2^3X if X refers to the bits per channel.

so 42-bit depth - way over that. Looks like 48-bit color is about 481 trillion colors... So around 60 trillion for 42-bit color, right?

https://www.cambridgeincolour.com/tutorials/bit-depth.htm

And what interface would it have had to use at that bit depth and resolution.

See here:
http://monitorinsider.com/cable_bandwidth.html

Sounds to me like something like that would have been completely unusable over an analog vga type signal.

The technology for something to supports those crazy specs did not even exist back then.

Even now, the higher end LCD can't even support that much bandwidth... And video cards look to be limited to 12bpc or 36-bit color.. and that is at probably a max of 1080p.

From looking up stuff, consumer monitors are going to be 8bpc, higher end 10bpc, and 12bpc is very rare.

So yeah, 20+ years ago and this sort of thing was not anywhere near being possible.

True that!

But no person in the world would be able to distinguish it from 24-bit color 😀

But then again - if the spoof was to be true, the CIA computers probably could've used all that resolution to find details .. 😉

Please use the "quote" option if asking questions to what I write - it will really up the chances of me noticing 😀

No idea. We don't even know how it would be divided on such card. 12bpc + 6bit alpha? 10bpc + 12bit alpha? Uneven bpc?

Well, modern monitors, with digital inputs, indeed support precisely defined number of colors - eg. 16777216.
CRT monitors, however, usually claimed infinite number of colors.

Im gonna stick with my IBM Bitchin’ Fast MDA card. The cursor blinks so fast it gives some people seizures.

Check out DOSBox Distro:

a lightweight Linux distro (tinycore) which boots off a usb flash drive and goes straight to DOSBox.

Make your dos retrogaming experience portable!

No. Just jumped down a rabbit trail into technical theory.

And I'm just smiling over here with my Bitchin' Fast! Audio card...

So, how fast it is?
If it can play the entire content of a 74-minute Compact Disk in less than 1 minute, then I want to buy that card as well!

For real, an ¡AudioLoca! card featuring the best audio chips of all time would be cool.

Lets see:
SB Pro/16
Real OPL3 and OPL2
Gravis Ultrasound
Roland LAPC-1
Roland SC-55

What else can we throw in there?
Disney Sound Source?
A3D and EAX support?
