This feature could be accessed under basic from the comunication software that came with the comptuer. The computer also came with a word processing program, a database and a spreadsheet.

The machine had some impressive hardware, but the processor was still clocked at only 1 MHz, making it moderate compared to its competitors.

  • Double sided 640kByte floppy disk drive
  • Integrated 1200/75 baud modem

Motorola 6809 CPU

The Motorola 6809 is an 8-bit microprocessor with some 16-bit features. It was designed by Motorola's Terry Ritter and Joel Boney and introduced in 1978. Although source compatible with the earlier Motorola 6800, the 6809 offered significant improvements over it and 8-bit contemporaries like the MOS Technology 6502, including a hardware multiplication instruction, 16-bit arithmetic, system and user stack registers allowing re-entrant code, improved interrupts, position-independent code and an orthogonal instruction set architecture with a comprehensive set of addressing modes.
