Running DOOM on an IBM RS/6000 Under AIX

I’ve been rather taken by NCommander’s YouTube channel lately, in which he regularly tries to build and run old versions of Unix and software for it. He’s run an old boxed version of Debian 2.1, Internet Explorer 5 for Unix, the first Linux live CD (Yggdrasil), and–get this–even a version of System V made for the Commodore Amiga that was officially published by Commodore! It comes out of the box with NetHack 3.0! (Warning: that one’s a seven hour live stream.)

A highlight of the channel that falls under our jurisdiction is him trying to get DOOM running on an old IBM machine running old IBM Unix. Over an hour long, the video is a long sequence of sadness, involving misconfiguring hostnames, getting X running, discovering that IBM’s C compiler costs about $2,500, running into basic C functions IBM didn’t implement, building OSS for AIX (and buying a $10 license for that), and then the issues with building and running the game itself. So yes, add it to the long list of devices that run DOOM, but at what cost?

Well, to NCommander, $10 plus several days of time. To you, about an hour of entertaining (somewhat) learning about obscure computing esoterica!

PS1 Rendering Quirks

via @doc on Twitter. PikumaLondon tweeted out a thread (unrolled) explaining, in general, how the original PlayStation rendered graphics, and the source of its distinctive graphic artifacts, specifically texture warping, pixelated textures, and jittery polygons. The Nintendo 64 didn’t have these problems, but also couldn’t draw as many polygons each frame.

The thread also links to developer David Colson’s efforts to create a PS1-style 3D fantasy console. I’m sure this isn’t interesting to everyone, but worry not, this blog isn’t going to become entirely low-level hardware rendering geekery. At least, not yet.

Nicole Express: Tengen’s NES Chips

The always-wonderful retro gaming and hardware info site Nicole Express has a great post about the chips that Tengen (a subsidiary of Atari) used in their cartridges! Tengen is a special case among NES developers, in that while a Nintendo licensee they got to use their own mapper, from Namco, but went and manufactured their own ASICs when they split off from Nintendo’s licensing program. The deets are all in the article!

Nicole Express’ archives are well worth a look, which among other items hosts their article on Zaxxon and Future Spy. They have interesting games to play on their itch.io page too! Have I used enough exclamation points yet?!
