8088 Corruption (2006 original presentation)

Google Video is shutting down, so I migrated this over. Original text from 2006:

Color video running at 30 frames per second, with audio, on an original 4.77MHz 8088 IBM PC Model 5150 with 640K RAM, CGA video, 10MB drive, and Sound Blaster Pro.

No tricks, this is for real! This kind of speed is only achievable using text mode (!) and 8088 assembler.

hey! I sometimes make console applications for fun in C# and what I do to make a smooth video or a nicely runnig puzzle game in that limited screenspace is that I render 2 frames everytime and compare the new one with the old one and only redraw the parts that changed. similar to what id software was doing with the first keen. is that possible on an 8088? or would it chop down performance too much? :)

[MobyGamer]

It's possible, but only for very limited deltas. The video footage I was working with had too much information change between frames, which would have been too much for the IBM PC I was working with.

I used an 8088 with CGA for several years, that's pretty impressive! I'm guessing they converted the video to an asm program and plotted only the deltas using direct access to the screen buffer...

[MobyGamer]

Actually, deltas would be too slow for the 8088 to process, and because so much content changes per frame, it wouldn't offer much compression anyway. I gave a presentation on how exactly 8088 Corruption works, which I'll upload to my channel soon.

I was impressed, but then at the end I saw the line about the video being rendered on a pc with a cga video card.

I shat bricks.

Yep i'm sure i've seen that person Yesterday,hehe. That is impressive,i had an XT before 13 years without knowing what it was but i was a kiddy and didn't knew how to use it and after years it gone for scrap. :( now i want one again to do such fun things!! Awesome demonstration!

This is actually really impressive for the age & limitations of the hardware. It has the same impact as the first time I saw the Amiga demo 'State of the Art' run off a single 800kb floppy disk on a 7Mhz Amiga 500. To put that into perspective, the music alone is ~250kb uncompressed. Great video, and thank you for uploading.

Well... I am impressed and surprised.

Thanks for sharing!
