The SixPakPlus is a multi-function memory expansion board designed for use
with the IBM PC, XT, and 100% compatibles running at 4.77 MHz.  In it's
standard cofiguration, it comes with anywhere between 64K and 384K of RAM
using industry standard 64K dynamic RAM chips; a Clock/Calander; a Serial Port
configurable as COM1: or COM2:; and a Parallel Port configurable as LPT1: or
LPT2:.  All memory installed on the SixPakPlus is designed to expand a PC to
it's 640K maximum.  It does not support Extended or EMS/EEMS type memory.

        6) Installed to Enable Clock/Calendar         (2C0)

    IRQ JUMPER BLOCK

        The IRQ block consists of three pairs of pins, labeled 3,4,7.
        Install a jumper at "3" if the Serial Port is configured as COM2,
        or at "4" if it is configured as COM1. Install a jumper at "7"
        if the Parallel Port is configured as LPT1.


RS-232 JUMPER BLOCK

    RS-232 configuration block is made up of six pairs of jumpers labeled 1-6.
    Their function is to minimize the need for making special I/O cables for
    some unique serial devices. The normal setting in nearly all cases is to
    install three jumpers on the even numbered options (2,4,&6). In rare
    instances, a device may require that the CTS, DSR, or DCD signals be
    forced true. In these cases, move the corresponding jumpers as follows:

        Move "2" to "1" to force True CTS
        Move "4" to "3" to force True DSR
        Move "6" to "5" to force True DCD
