David criticizes the keyboard's software for being too generous when handing out praise, disincentivizing kids from wanting to do better. In particular, when he plays the Dora the Explorer cartridge, he believes that Dora should say "You stink! You should try harder!" whenever the player gets a low score.
Staying with Dora the Explorer, he states that he's sadly all too familiar with Dora's songs, since he watched the show with his daughter when she was little.
While playing the "Pop Hits" cartridge, David has one of his cats "play" the keyboard.
David shows footage of someone dressed as Darth Vader playing bagpipes while riding a unicycle.
From "Early 8 Bit Sound Digitisers", the highly dubious musical capabilities of the Covox Voicemaster. Hum Along creates what sounds like digital farting, which David indicates his reaction to using an emoji sticking its fingers in its ears. As for Composer, it can't automatically register tempo at all and does an incredibly poor job of recognising pitch even when the audio source is a keyboard, resulting in speedy collections of random notes vaguely resembling the user input at best. Even a demo file on the Apple II version sounds terrible, suggesting that not even the programmers could get it working properly.
From "How Speech Synthesizers Work", as David is recalling the use of 1980s speech synthesizer software, he mentions its use to make prank calls. He then demonstrates one:
[David is seen using a 1980s era landline phone, pressing "0-1-1-4-4" on the buttons]note 011 is the international access code in the United States and the rest of the North American Numbering Plan, 44 is the country code for the United Kingdom [cut to the Techmoan studio, where a phone rings] Mat Taylor: Hello? SAM: HEY TECHMOAN! I JUST HAVE TO TELL YOU THAT YOUR YOUTUBE CHANNEL IS TOTAL CRAAAAAP! Mat: [hangs up] Flippin' idiot!
After having issues with the monitor board for the arcade game Moon Base, David gives the board to Sark at the Vintage Computer Festival in Chicago - but not before jokingly handing it to Adrian Black, who had already tried to fix it for David. Adrian rejects it on sight, calling it "cursed". David starts to wonder if he's right when, after Sark successfully fixed the board, he accidentally breaks the tube of the CRT monitor (mind you, he'd previously taken the monitor in and out of the machine dozens of times with no issues). At least he had a spare machine to get it fully working, but still.
, the metal shield falls off. David's reaction: "Well, that's just lovely."
