Scanntronik Manuals
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 AUTOMODEM (Model 1650)
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 Commodore VICMODEM (Model 1600)
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 Commodore Modem/1200 (Model 1670)
The Commodore 1670, also known as the “Modem/1200”, is Commodore’s first Hayes-compatible modem: It connects directly to the phone line and supports pulse and tone dialing for 1200 and 300 baud duplex connections. There were two revisions, the original 1670 and the “new” 1670, a.k.a. CR-1670. (The unit in this article is the later revision.)
The Commodore Modem/300 (Model 1660)
The Commodore 1660, also known as the “Modem/300”, is Commodore’s first full-featured modem: It connects directly to the phone line and supports pulse and tone dialing for 300 baud duplex connections.

This is the previously unpublished “Commodore 264 Series Preliminary Users Manual”, a prerelease version of the manual of what came to be the Commodore Plus/4.
Third Party Disk Drives for the C64: The “Technica”
I have previously analyzed the ROM images of some third party disk drives for the Commodore 64: The result was that most of them were just using the original binaries with some obfuscation, and some with some added features. This time, let’s look at another drive, the “Technica”, which is a little special in this regard.

Making of the Book “Anatomy of the 4040 Disk Drive”
To my surprise, Hilaire Gagne, the author of “Anatomy of the 4040 Disk Drive”, commented on my blog post about the reconstruction of his book.

Commodore Plus/4, C116, C16 (TED) Technical Documents
The Commodore Plus/4, the C16 and the C116 from 1984 were members of the 6502-based “TED” series, named after the 7360 TED (“Text Editing Device”) video controller. The TED systems were basically the low-cost cousins of the C64: The overall system architecture and the video chip are very similar to the C64’s, but they lack certain features like hardware sprites. On the other hand, there are some added features like extra colors and more control over the internal timing of the video chip.
HFS+ File System Analysis and Forensics with fileXray
Modern filesystems are highly optimized database systems that are a core function of modern operating systems. They allow concurrent access by many CPUs, they keep locality up and fragementation down, and they can recover from crashes guaranteeing consistent data structures.
