FBE H89PIP

The H89PIP is an add-on circuit card for the Heath/Zenith H89/Z89 series of all-in-one computers. The card uses an 8255 Programmable Parallel Interface chip to provide two 8-bit Parallel Interface Ports. One port is buffered for use as a Centronics’" Printer Interface. The other port is "bare" and may be used for parallel input or output.

The H89PIP may be installed on either the "right side" (P504-P510 or P505-P511) or the "left side" (P501-P507, P502-P508, or P503-P509) internal bus. When installed on the left, a 3-wire cable (included) is run to the right side to bring in needed I/O control signals.
