Apart from the Sierra Christmas cards there were many more standalone free gimmicks and games released by Sierra. Two of those were the Astro Chicken games from the Space Quest series. What did they look like and how did they play? Let's find out today.

The 3D Wireframe cube is part of every demoscene coder’s learning curve. Today I want to talk you through the principles of 3D programming in general and especially the idea of fixed point maths, where you use integers instead of floating point numbers to represent fractions. Older CPUs before the 80486 had no built in floating point support, and even the FPUs were quite often rather slow and hard to program for, if available at all. So people had to opt to use integer arithmetics in stead. But 3D graphics requires fractional numbers, so how do we get both things together and manage to display a rotating wireframe cube on our MS DOS machine?

The main issue with the Commodore 8050 and 8250 drives is: How do you get data onto them? The units use 100tpi floppy drives that are incompatible to the regular 48tpi and 96tpi disk drives used in the 1541 and in PC DD and HD drives. So there is no chance using those. However there is the ZoomFloppy, which is an implementation of the XUM1541 interface and it comes with an optional IEE488 plug! We can attach the 8050 to that, and use the OpenCBM tools to read and write data to and from the floppies.

The cheap, Chinese action cam that I have since a few months has one more problem: it's quick release holder broke. It's no wonder that it broke, but getting a replacement will not be possible. So my friend Olli did the next best thing. He designed and 3d printed a new one!
