  • AT&T Dataphone

    AT&T Dataphone
    sourceAT&T designed its Dataphone, the first commercial modem, specifically for converting digital computer data to analog signals for transmission across its long distance network. Outside manufacturers incorporated Bell Laboratories´ digital data sets into commercial products. The development of equalization techniques and bandwidth-conserving modulation systems improved transmission efficiency in national and global systems.

  • Macintosh 128k

    Macintosh 128k
    sourceThe centerpiece of the machine was a Motorola 68000 microprocessor running at 7.8336 MHz, connected to 128 KB RAM shared by the processor and the display controller. The boot procedure and some operating system routines were contained in an additional 64 KB ROM chip. Apple did not offer RAM upgrades. The 68000 and video controller took turns accessing DRAM every four CPU cycles during display of the frame buffer, while the 68000 had unrestricted access to DRAM during vertical and horizontal bla
