  • Hi,

     

    Maybe you already discovered but this is what I can mention you.

    The Intel 8255 is a Programmable Peripheral Interface: parallel port chip.

    You might find one in old PCs like PC/XT with 8008, 8080A, 8086 or 8088 processors (1986-ish...).

    According to Wikipedia these were also used in Z80 systems.
