Some Assembly Required
The 6502’s “illegal” opcodes were of intense interest to home computer enthusiasts, and analyses were published in various magazines. But one would have never expected a company like Siemens to document illegal opcodes in a programming manual from 1980.
The Siemens PC 100 was a version of the 6502-based “AIM-65” SBC in a case and with slightly modified ROMs. Siemens offered a set of German-language manuals, which included translated Assembler (MOS Resident Assembler) and BASIC (Microsoft BASIC) manuals, but also a general manual (“Bedienungsanleitung”).
In Folge 017 des C64-Podcasts Brotkastenfreunde bin ich diesmal Gast.
Am 25. März 1985 kam das zweite 64’er Sonderheft mit dem Thema Abenteuerspiele raus. Genau 40 Jahre später ist es nun als HTML und PDF online verfügbar – im Kontext des Projekts 64er-magazin.de. Der Drachenreiter auf dem Original-Titelblatt ist der damals 18jährige Boris Schneider-Johne – wer genau schaut, wird auf der Website erkennen, dass wir das Bild aktualisiert haben:
Zum 40jährigen Jubiläum des 64’er Magazins präsentieren wir das Kunstprojekt www.64er-magazin.de: eine Website, die so tut, als wäre 1984. Exakt 40 Jahre nach der ursprünglichen Veröffentlichung erscheint hier jeden Monat eine neue Ausgabe:
This post is about an upcoming talk in German.
The Deutsches Museum in Munich (Germany) has a new art installation as part of the reopened Electronics exhibition: The “Schrott-Tornado”, a tornado-shaped sculpture made from scrap electronics. There is (at least) one item in it that is most definitely not trash.
I have created darmok.com, a website that lets you share common memes in the Tamarian language.
We have recently dissected and dumped the Level 2 “Plus” version of HP’s PostScript cartridge series. This time, we will look at the earlier Level 1 “PostScript Cartridge”.
The German company “Scanntronik” offered a lot of high-quality hardware and software for the Commodore 64 series computers, most in the space of graphics and desktop publishing. They are well-known for their Pagefox and Printfox software as well as their Handyscanner 64 hardware. This page offers most of the German-language manuals from across their product range as searchable PDFs.
The Commodore 1650, also known as the “AUTOMODEM”, is Commodore’s first full modem directly connected to the phone line. It supports pulse dialing in software and 300 baud duplex connections.
The 1963 book “Robots and Electronic Brains” (by Robert Scharff) from the “How and Why Wonder Books” series is an early children’s book about computers. Let’s look at some of the interesting contents – and how the German translation “Was ist was: Roboter und Elektronengehirne” from 1967 changed some details.
This article explains a setup and workflow for digitizing analog video (e.g. VHS, Beta, Video 2000, LaserDisc, …) using a Mac and digital camcorder – in high quality and with interlacing intact; optimized for archival. We will use a old-school digital camcorder (they are cheap!) to convert the analog signal to a high-quality digital “DV” stream and then record the DV stream on a Mac using a FireWire connection.
Many pre-recorded MiniDiscs are rare and expensive. An extra rare special case is the dummy promo copy of Michael Jackson’s “Dangerous”, which we will dissect in this article.
The Commodore 1600, also known as the “VICMODEM”, is Commodore’s very first modem (1982): It supports 300 baud duplex connections, and is connected to an existing telephone’s handset connector instead of the phone line. This kept the price down, but required the user to dial manually through the phone.
The HP LaserJet III laser printer from 1990 used the “Printer Command Language” PCL 5 by default, but could be upgraded with the “HP PostScript Cartridge Plus” cartridge, which contained 2 MB of ROM with Adobe’s PostScript Level 2 rasterizer. Let’s look at the ROM contents and some of its hidden gems.
CCGMS Future 0.2 was just released. It adds 80 columns support, a true ASCII charset (in 80c mode), and bug fixes.
The Punter file transfer protocol (“New Punter”/“Punter C1”) is an alternative to the XMODEM family of protocols, which was and still is very popular on BBSes for Commodore computers. It is notorious for being badly documented. Let’s fix that.
The user port of the Commodore 64 exposes a TTL-level RS-232 serial port that supports up to 1200 baud1. In 1997, Daniel Dallmann came up with a very sophisticated trick that allowed sending and receiving at 9600 baud2, using slightly different wiring and a dedicated driver. This “UP9600” wiring has become the de-facto standard for all modern accessories, like C64 WiFi modems. Let’s see how UP9600 works.
