My last blog post showed the Zuse Z3 (1939-1941), the world’s first working digital Turing-complete computer. Let’s go back two more steps: The Zuse Z1 (1936-1938) shared its design with the Z3: It read its program from punched film and used floating point as its internal representation of numbers. But since it was all mechanical, it never worked reliably.
This article is in German, since it is about the German TV show “Supergrips” and how the scoreboard was implemented.
Here are all three volumes of the original 1985 edition of Inside Macintosh as a searchable PDF:
I converted the first issue of the German Commodore 64 magazine 64’er into a searchable PDF:
If you disassemble any version of Microsoft BASIC for 6502, you’ll find this code in a function that normalizes the (simulated) floating point accumulator:
Everyone and their grandmother builds Linux kernels. Many people build BSD, and some brave men even compile the OS X kernel every now and then. Why not compile your own Solaris kernel for a change?
If you type “WAIT6502,1” into a Commodore PET with BASIC V2 (1979), it will show the string “MICROSOFT!” at the top left corner of the screen. Legend has it Bill Gates himself inserted this easter egg “after he had had an argument with Commodore founder Jack Tramiel”, “just in case Commodore ever tried to claim that the code wasn’t from Microsoft”.
After the disaster of the original Xbox, Microsoft put a lot of effort in designing what is probably the most sophisticated consumer hardware security system to date. We present its design, its implementation, its weaknesses, how it was hacked, and how to do it better next time.
The original NMOS version of the MOS 6502, used in computers like the Commodore 64, the Apple II and the Nintendo Entertainment System (NES), is well-known for its illegal opcodes: Out of 256 possible opcodes, 151 are defined by the architecture, but many of the remaining 105 undefined opcodes do useful things.
