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.

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".

This operating manual is furnished with the AEA PK-64 Pakratt Data Controller. It is designed to give you an introductory idea of what Packet Radio is all about. It is not intended to give a comprehensive treatment of the subject - there is a reading bibliography of many fine articles and books in the appendix to this manual.

You will learn in the remainder of this introduction a little bit about what packet radio is, what some of the terms are (there is a glossary in the appendix), what happens in a typical QSO and what appears on the screen.
You will be anxious to get on the air in a hurry if you are an average ham. You probably won't want to spend any time reading the manual before doing so. You may not have even gotten this far. If you have, be advised that the chapter titled "Quick Check and Sneak Packet Preview" will give you the thrill of a very quick way to get some of the locai packet activity to print on your screen.

Thank you for your purchase of our PROMQUEEN 64 ROM software development system. The cartridge and its software are designed for versatility, so you must bear with us as we attempt to acquaint you with its many features. To use the cartridge properly you must understand three categories of information, which are:

1. The three modes of the cartridge controlled by the 3-position toggle switch.

2. Selection of EPROM type by appropriate setting of the matrix switch.

3. Use of the software for manipulation of hexadecimal lists and communications to and from other devices such as the printer, RS 232 interface, cassette recorder, and disk drive.

You are assumed to be familiar with number bases and the hexadecimal system, which is most natural for microprocessor work. Please read pages 215-217 of the Commodore 64 Programmer's Reference Guide if you are unfamiliar with this.

This manual thus consists of four parts, including an inevitable catch-all section for miscellaneous information. It is written in tutorial style to give you hands on experience with each capability of the cartridge. Please take the time to work along with the exercises as they are given. You'll gain a thorough understanding of the cartridge as well as ability to use it creatively. You'll also save on wasted time or telephone calls.

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.

This is the manual for the Turbo64 accelerator cartridge plus some addendums, pictures and the floppy disk that comes with the cartridge.  Here is a quote from the manuals introduction:
