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.
CCGMS Future 0.2
CCGMS Future 0.2 was just released. It adds 80 columns support, a true ASCII charset (in 80c mode), and bug fixes.
The Punter C1 Protocol
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.
UP9600: How to Bit-Bang 9600 Baud RS-232 on the C64
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.
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.
Announcing CCGMS Future 0.1
The CCGMS Terminal Program for the Commodore 64 is maintained again, and there is a new version: CCGMS Future 0.1, with bug fixes and new features.
