  • Build a Swtpc 6800
    Southwest Technical Products Corporation 6800 Computer System The Southwest Technical Products 6800 computer system is based upon the Motorola MC6800 microprocessor unit (MPU) and its matching support devices. The 6800 system was chosen for our computer because this set of parts is currently in our opinion the "Benchmark Family" for microprocessor computer systems. It makes it possible for us to provide you with an outstanding computer system having a minimum of parts, but with outstanding versatility and ease of use. In addition to the outstanding hardware system, the Motorola 6800 has without question the most complete set of documentation yet made available for a microprocessor system. The 714 page Applications Manual, for example, contains material on programming techniques, system organization, input/output techniques, hardware characteristics, peripheral control techniques, and more. Also available is a Programmers Manual which details the various types of software available for the system and instructions for programming and using the unique interface system that is part of the 6800 system. The M6800 family of parts minimizes the number of, required components and support parts, provides extremely simple interfacing to external devices and has outstanding documentation. The MC6800 is an eight-bit parallel microprocessor with addressing capability of up to 45,536 words (BYTES) of data. The system is TTL compatible requiring only a single fine-volt power supply. All devices and memory in the 6800 computer family are connected to an 8-bit bi-directional data bus. In addition to this a 16-bit address bus is provided to specify memory location. This later bus is also used as a tool to specify the particular input/ output device to be selected when the 6800 family interface devices are used.

  • SWTPC PR-40 Alphanumeric Printer Assembly Instructions
    SWTPC PR-40 Alphanumeric Printer Assembly Instructions The SWTPC PR-40 Printer kit is a 5 X 7 dot matrix impact printer similar in operation to the well known Centronics printers. It prints the 64 character upper case ASCII set with 40 characters/line at a rate of 75 lines/minute on standard 3 7/8" wide rolls of adding machine paper. One complete line is printed at a time from an internal forty character line buffer memory. Printing takes place either on receipt of a carriage return or automatically whenever the line buffer memory is filled. The printer can accept character data as fast as one character per microsecond or as slow as you wish to send it. The printer's seven parallel data lines are TTL compatible and may be enabled by a single "data ready" control line or by separate "data ready" and "data accepted" handshake control lines. This universal approach makes the printer compatible with all computer and terminal systems having an eight bit parallel interface; including of course the MITS 8800 and SWTPC 6800 computer systems just to mention a few. The printer mechanism is attached to a black anodized aluminum chassis with front trim panel which houses the unit's circuitry including its own 120/240 VAC 50 to 60 Hz power supply. This makes the printer's overall dimensions 9 5/8" wide X 10 1/2" deep X 8 3/4" high. Each unit is shipped with one ribbon and one roll of paper. Extra ribbons are available from us while the standard adding machine paper may be purchased in office supply stores.
