Wow, super impressive and cool. He makes it look so easy, but I know from personal experience it's not. He's got some real patience, persistence, and expertise to produce such a smooth and polished demonstration. The minimap navigation looks highly useful given the low resolution.
Story time: Back in highschool, I downloaded and printed TI-82 source code for a version of DOOM. The thing is, I had no money to acquire the requisite serial cable, nor know-how about how to connect it to a Mac to load anything. A Macintosh Performa 550 was the only computer I had access to, and possibly it wasn't even supported by TI at the time (almost nothing I really wanted was! The chronic limitations did encourage me to become really proficient with HyperCard, though).
I carefully entered the 45 pages of source code into the calculator, double checked it, and guess what happened next? -- it didn't work! I was pretty disappointed but not entirely surprised. Eventually, without a path forward, I abandoned the quest.
Afterthought: Is there a similar way to get an original PalmPilot onto Wi-Fi and the Internet?
I had a similar problem with the cable for the HP 48. However, in this case it turned out that the serial pinout was known and a connector could be made out of a PC motherboard connector (for speakers, etc.) plus a cut-up RS232 cable. It was nice to be able to download stuff into my calculator using a PC serial transfer program (I forget the protocol.)
I also made a cable for my HP 48SX. I also used individual female pins from some other connector, soldered the wires to them and then I molded an epoxy "body" on top of them while they were plugged into the calculator (talk about living on the edge).
I still have the calculator and the cable. For some time the calculator had some display issues after being accidentally dropped but I powered it up a few months back and it seems to have fixed itself. I recall how much I wanted to get one back in the day and how much fun it was.
A video by benryves that looks at an ESP8266-based WiFi "modem" for TI graphing calculators and how it can be used to connect a calculator to the Internet.

Edit: Apparently the answer is "yes", and no ESP32 hacking required. https://www.oreilly.com/library/view/palm-and-treo/059610054....
