- On the Trail of the Oregon Trail, Part 1 (filfre.net)
I recently got a copy of 1001 Video Games You Must Play Before You Die. It’s not really a very good book, for reasons that are interesting on their own and that I hope to talk about in another post very soon. Right now, though, I want to talk about the very first entry in the book, on The Oregon Trail, because that entry sent me down a rabbit hole from which I have only just emerged, blinking and reconsidering the history of interactive narrative.

In the midst of the cold but snowless Minnesota December of 1971, a student teacher named Don Rawitsch wheeled a bulky teletypewriter into his 8th grade history class. Students gathered around curiously as he plugged in power and phone cables, switched on the humming machine, and dialed the number on a rotary pad that would connect him to a $100,000 minicomputer fifty miles away. The students, Mr. Rawitsch said, were going to play a game.

- Two interesting XOR circuits inside the Intel 386 processor (righto.com)
Intel’s 386 processor (1985) was an important advance in the x86 architecture, not only moving to a 32-bit processor but also switching to a CMOS implementation. I’ve been reverse-engineering parts of the 386 chip and came across two interesting and completely different circuits that the 386 uses to implement an XOR gate: one uses standard-cell logic while the other uses pass-transistor logic. In this article, I take a look at those circuits.
