In 1980, Intel announced the 8087 Math Coprocessor, a chip that made floating-point 100 times faster. I opened up the chip, took photos of the silicon structures, and analyzed its circuitry. It's a very complex chip for its time. Let's take a look inside...

Sometimes I try using AI to generate assembly code, and the results are always funny, no matter what I ask for

2 years and 8 months since LUNARK came out. Hard to believe.
I spent 4+ years mostly solo on this project - rotoscoping, coding, composing the OST - and your support made the difference! Thank you for playing my little cinematic-platformer tribute 🥰

I'm looking for someone with an IDT WinChip2 PC willing to run a couple of benchmarks for my latest FastDoom work. Also looking for someone with an IBM NexGen, though I imagine that's about as hard to find as a unicorn.

MMX optimized span renderer (2 pixels per loop) now works in FastDoom’s backbuffered modes. Benchmarks on a Pentium MMX 200 @ 640×400 (Ultimate Doom demo3):
- 486 code path: 49.237 fps
- MMX code path: 56.031 fps (+13.8%)
Really happy with the results, although it’s still not 100% optimized.

Here's a visualization of the EGA's VRAM data bus.
Each graphics controller controllers two planes, and has a 16-bit data path to do so, letting the EGA read all four planes at once, which is nice.

Turkey day fun: You can interface I2C devices with a PC’s SMBUS as long as there are no address conflicts. This is an SSD1306 based 128x32 monochrome OLED on an abit bp6 motherboard (running T2 SDE Linux). SMBCON pinout and gist follow. It is device ‘3c’ here.

First tests of the MMX column rendering code in FastDoom (VBE2 backbuffered modes, 640x400), tested on an Intel Pentium MMX 200:
Unrolled non MMX code: 49.872 fps
Rolled 2-pixels-per-loop MMX code: 51.487 fps (+3.2%)
So it’s a bit faster. I think I'll get a bigger speed-up with MMX span rendering.

2025 Endurance Drivers Championship completed. What started as a childhood game (IndyCar Racing, Gran Turismo 2, …) ended up becoming reality. A dream come true, I’m eternally grateful. And on top of that, we finished third in our category!
