  1. Preserving Great Tech For Posterity — the 6502

    trebonian writes "For great old hardware products like the MOS 6502 (used in the Apple II, the C64, the Nintendo NES), the details of the designs have been lost or forgotten. While there have been great efforts to reverse engineer the 6502 from the outside, there has not been the hardware equivalent of the source code — until now. As Russell Cox states: 'A team of three people accumulated a bunch of 6502 chips, applied sulfuric acid to them to strip the casing and expose the actual chips, used a high-resolution photomicroscope to scan the chips, applied computer graphics techniques to build a vector representation of the chip, and finally derived from the vector form what amounts to the circuit diagram of the chip: a list of all 3,510 transistors with inputs, outputs, and what they're connected to. Combining that with a fairly generic (and, as these things go, trivial) "transistor circuit" simulator written in JavaScript and some HTML5 goodness, they created an animated 6502 web page that lets you watch the voltages race around the chip as it executes. For more, see their web site visual6502.org.'"

    jacoplane writes "You may remember Rob Pike from his Slashdot interview. Since his interview, his two-dimensional text editors have experienced many improvements and ports including license improvements. A port to Inferno has been around for awhile. Recently a standalone version has been made for Windows based on the Inferno port. Linux users are in luck as the native port is now legally distributable."
