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.

Congratulations on having purchased a serial, impact dot matrix printer that offers you more quality, greater flexibility and convenience, and superior reliability than you could find in any other printer in the same price range. As you already know (or are about to learn), the Gemini-lox and Gemini-15X let you print both regular and italicized alphabets, as well as normal, elite (smaller), condensed, enlarged, emphasized, and double-strike characters. You can print on regular stationery, multiple-sheet forms, fanfold computer paper, or paper fed from a roll (European style).

The graphics capability provided by the Gemini printers is limited only by your graphic talents, and includes three bit-image modes: Low Resolution (60 by 72 dots per square inch), High Resolution (120 by 144) and Ultra High Resolution (240 by 144). With all this printing power at your fingertips, what are you waiting for? Let’s get started!

This User’s Manual is organized to serve both the first-time user and the sophisticated computer buff. The first five chapters provide the basics you need for putting your printer to work in most home and office applications. Chapters 6 through 10 deliver information for intermediate and advanced users, supported by technically rich appendices. If you are a beginner, you might want to look at Chapters 6-10 sometime in the future, when your curiosity about how the printer does what it does has replaced your initial interest in what it can do.

TURBO PROCESSOR 4 Mhz 16 Bit Expansion card for the Commodore C64

We congratulate you on your purchase of one of the best hardware add-ons available for Commodore C64 . With Turbo 64 your Computer becomes one of the most efficient home computers in the world.

To develop the TURBO PROCESSOR it needed a lot of research and time as we wanted to develop a card which is simply plugged into the expansion port and runs. We also discovered that one C64 is not the same as another C64. There are many different versions with different timings, i.e. a C64 made in England is different from the one made in USA Therefore you will find on the PCB of TURBO PROCESSOR three trim pots for adjusting the timing to suit your own C64.

Xetec's Graphics Printer Interface (GPI ) is designed to allow the Commodore VIC 20 or C-64 to print with any parallel printer that is Centronics compatible. It is primarily intended as a substitute for the Commodore
1525 printer, and therefore can be configured to make your printer work just the same. It has special functions , however, which the 1525 cannot perform. If you plan to make use of these features, a thorough reading of this manual is suggested. Otherwise, a skim will probably get you up and running.
