  • Z80 Family Reunion Discovered In Old PoS Card Swiper

    Ben Heck found an old card swipe point of sale box at the Goodwill store, took it home, and tore it down to see what was inside.



    He found a completely serviceable single board computer based on the Z80.

    In fact, there's a whole family of four Z80 chips: the CPU itself, the DART chip (dual UART), the PIO chip (parallel input/output interface), and the CTC chip (counter/timer circuit).

    That's not all — there's a landline telephone modem, a real time clock, 32K of RAM and UV-EPROM.

    The second PCB of this assembly holds a hefty sixteen-key keypad and a sixteen-character vacuum fluorescent alphanumeric display.

    All this for the bargain price of $2.99.
