This documentation was provided by one of our users (thank you Jeff) that explains the use of a hardware dongle by Datalock.  Here is an excerpt from the documentation:

Datalock security keys are small plastic devices which plug into the joystick port. The program you want to protect is made to read the unique circuit inside the key. If the correct key is not present, the program will not work.

EPROMMER 64 is a multifeature, low price EPROM programmer for the 64/128. It connects to the user port of the computer and comes with a comprehensive, menu driven utility program supporting all standard features for reading, programming, and checking EPROMS.

The unit supports a range of devices from 32k up to 256k. Multiple program voltages of 5v, 12.5v, 21v, and 25v make the unit more versatile then others generally available. EEPROMs can also be programmed and erased with the EPROMMER 64.

EPROMMER 64 is built on a highgrade PCB with quality components throughout including a 28pin zero insertion force socket.

Welcome to the EPROM PROGRAMMERS HANDBOOK! This unique book is for anyone who wants to learn how to program EPROMs for the Commodore 64. In this book we assume that you have some general experience with your C64 already. Some experience with machine language and hexadecimal will help you pick up the concepts faster. You'll need an EPROM programmer too, of course. The EPROM programmer we use here at CSM is the PROMENADE Cl from Jason-Ranheim. We feel you just can't buy a better programmer for the C64. Although the examples in the book are based on the PROMENADE, you should be able to adapt the commands to your programmer if you have a different model.

Congratulations on your purchase of one of the most long-awaited computers in the history of computing! The MEGA65 is community designed, and based on the never-released Commodore® 651 computer; a computer designed in 1989 and intended for public release in 1990. Decades have passed, and we have endeavoured to invoke memories of an earlier time when computers were simple and friendly. They were not only simple to operate and understand, but friendly and approachable for new users.

USI International created Mitey Mo because we felt that sending and receiving information with computers over phone lines (telecommunicating) should be easy, inexpensive, and fun. We wanted a modem and software package friendly enough for the novice user and advanced enough for the most sophisticated user regardless of age. We started with this mighty little modem that combines the latest in technology with the convenience of small size and easy installation. To that we added software written specifically for this modem that gives directions on the screen in plain English. We wrote a manual that is thorough, easy to understand, and enjoyable to read. Further more, we've included phone cables and a function key template in our package to make it complete. Our total system makes it easy for you to get started while at the same time bringing out the full capacity of your Commodore 64.

Users manual for the MMC Replay (updated 2/7/2008 - BIOS v0.51).

The MSD SUPER DISK DRIVE is perhaps the most versatile and efficient disk drive built for the Commodore series of personal and business computers. The MSD SUPER DISK DRIVE is unique in that it features both serial and IEEE bus interfaces in one unit. The result of this flexibility is that the MSD SUPER DISK DRIVE is compatible with the Commodore SERIES 2001 {with BASIC Version 3.0 or higher), SERIES 3000 (with BASIC Version 3.0 or higher), SERIES 4000 (with BASIC Version 4.0), SERIES 8000 (with BASIC Version 4.0), COMMODORE 64 and VIC 20 computers. The wide range of compatibility is accomplished by providing a dual serial computer interface and an IEEE parallel interface. These two interfacing methods allow multiple disx drives /and printers to share the bus concurrently. The use of the parallel interface provides for significantly faster data transfer over the serial bus interface. With the addition of MSD's optional CIE or VIE interface board (IEEE interfaces for Commodore 64 or VIC 20) that plugs into the expansion port of the Commodore 64 or VIC 20 respectively, the user is even able to obtain this parallel speed enhancment on the Commodore 64 or VIC 20. The versatility is enhanced even more by the fact that the MSD SUPER DISK DRIVE is upward compatible with the commodore 2040 disk drive and read/write compatible with the Commodore 2031, 4040, 1540 and 1541 disk drives. This means that disks that were saved from the 2040 can be read by the MSD SUPER DISK DRIVE and disks that have been created on the 2331, 4040, 1540 and 1541 can be both read from and written to without any harm to existing programs on the disk.

Congratulations on your purchase of the NEOS MOUSE & CHEESE.  The NEOS MOUSE is an excellent input device with which you can give various instructions singlehanded to a computer while watching the TV screen,etc.  Before using the mouse read this manual carefully to get the most out of the NEOS mouse and the software ''CHEESE".
