Also there some "C icks" (to me, I'm very picky and used to know the standard awfully well from answering many SO questions) that you might want to look into. The two I remember now are the casting of `void` pointers from allocation functions, and (worse) the assumption that "all bits zero" is how a NULL pointer is represented.

Found a tiny typo, this sentence from quite early (page 17):

Notice how apparently wasteful this file format is: some of the triplets contain only byte.

I think the word "one" is missing before the final "byte".

There was some kind of editing snafu though, the loop header in the big (first) code block reads:

    for (i = 0; i < 10; i++, nuke_count++)

    for (;;)

I also have read their backstory/naming thing [1] several times but I still don't quite get it. I first thought they were related to the historical Grog, but that was a misunderstanding. I think.

I'm no native speaker but that is backwards, right? Shouldn't it be overstated if it was a success?

I love seeing new games for "retro" machines, it's awesome that people keep pouring time and love into them after all these years.

I'm not super familiar with 8-bit Atari machines, and found the designation "classic unmodified 8-bit ATARI XL/XE" a bit imprecise. Tried looking up specs on Wikipedia [1] but was unsure what to settle on. Perhaps the original 1200XL would match? Or the 800XL which seems to improve on the 1200XL even though the naming suggests the opposite ... Or the 65XE, or both then I guess since the latter is compatible with the 800XL, but in an updated case?

If my math is right it seems the cost in material for the printed part is around $5 which seems ridiculously cheap for a custom-designed and adapted solution like this. Nice!

I wish the author had spent a few words extra to motivate why it needs to be in PETG filament for "heat resistance", is the regular PLA limit of ~55 degrees Celsius not okay for a desktop accessory? I guess if it's in direct sunlight that might be exceeded, or perhaps if the laptop runs very hot?

It turns out that there are various models for the number of continents, and that is (phew) known in Spanish, too. See the Wikipedia page [1] (link to Spanish version) for instance. This is for European Spanish though, but I couldn't find a version of the page in es-AR.

But this really is a stretch:

The Z80 Membership Card itself is a stand-alone single-board computer that can "power up" your projects, like the Parallax BASIC Stamps or Arduino microcomputers.

Both of those are very commonly called microcontrollers, not microcomputers, since they have all of those extra chips merged into the single package of the CPU.

Take a look at the Arduino Uno [1] which is a very typical (if old) example: you will see that the board is not covered in ICs from edge to edge, since all of the main functionality is in the single-chip microcontroller. I think the second big-ish package visible is for the USB, but that also disappears on more modern controllers with on-board support for USB.

I did find the projects "user-facing" home page [1] which was nice. I found it rather hard to find a link from that to the code on GitHub, which was surprising.
