The original space invaders speeds up gradually as you kill the invaders. But this wasn’t an intentional feature- the game is just speeding up because it has fewer things to render on the screen.

Wow! A French court has blocked the auction of the Pascaline calculator. The auction of Parcé's many books is happening right now, but the calculator is not part of it. www.purdueexponent.org/news/nationa...

Here you go. It was a properly produced thing, but I don’t know by whom. Here it is on a piece of A4 paper. It was just transparent enough to pencil trace over pictures, and the pencil could be washed off. As you can see, I was into maps.

I just learned about this and had to make my own: Tecmo's Famicom graph paper! youtube.com/shorts/baAMH... I'm a sucker for hyper-specific-use-case graph paper.

I have made a reasonable facsimile of this sprite paper (US letter size). Please feel free to use.

Strange phenomenon: Every time I post a new video, I lose subscribers. My interpretation: There are some subscribers who aren't really into me anymore. But they don't seek out my channel just to unsubscribe. They will only unsubscribe when they are reminded of me, which only happens when I post.

New video: I went to see the Pascaline! They did not let me touch it. youtu.be/CROrLQpN6dc

Just posted at @archive.org: instructions for the transparent "Pascal-type calculator" (also called the SEE calculator). archive.org/details/pasc...

On an auction site someone is claiming to have a Comptometer for sale, but the picture is some kind of AI-generated rubbish. I don't see the point, but it makes for a fun game: How many errors can you spot?

The pascaline is in New York! No original stylus though 👎

Just received in the mail the ultimate Chisanbop holy grail- the blue “Stage 2” book by Pai and Lieberthal! I thought it was never published- I said in my video it was never written. But Randi found a copy at her mom’s house! Thanks again Randi!

New archival project: the Lawson Perspective Charts! It's a set of big (25x22in) charts for perspective drawing. Eight charts, various angles to the plane & horizon. With original instructions! The highest quality scans I could muster. I'll make a video when I have time. @archive.org links below
