| Wow, super impressive and cool. He makes it look so easy, but I

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

| be able to download stuff into my calculator using a PC serial
| transfer program (I forget the protocol.)

| 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.
