    The 7D11 ($2,915 in 1983) was a digital delay, the 7D15 ($3,020) was a 225 MHz counter/timer, the 7D13 ($1,105) was a multimeter, and the 7D12/M2 ($2,815) was a sample-and-hold with an analog-to-digital converter. More exotic digital plug ins used the mainframe oscilloscope as a mere display unit. The 7D01 and 7D02 were logic analyzer plug ins.

    In either mode, a timer can generate an interrupt when it has counted down to zero. Timer 2 functions as an interval counter or a pulse counter. If operating as an interval counter, timer 2 is driven by the microprocessor's PHI2 clock source. As a pulse counter, timer 2 is triggered by an external pulse source on the chip's PB6 line.

    Among them were the Z80 CTC (counter/timer), Z80 DMA [15] (direct memory access), Z80 DART (dual asynchronous receiver–transmitter), Z80 SIO (synchronous communication controller), and Z80 PIO (parallel input/output). The Z80 was officially launched in July 1976. [16] One of the first customers was a buyer who, unknown to Zilog, worked for NEC.
