    CP/M: The Page Pin from the ROM needs to be connected to the Page Pin on the RAM.  If you have the Backplane Pro and have installed the double header pins supplied with that then nothing further needs to be done.

    Configuration

    jumpers1.jpg

    All four jumers to right hand setting.
    Top 3 jumpers set start address to 0x0000.
    Bottom jumper sets lower 32k to be paged in or out from Pageable ROM board.

    Note that the B option for BASIC will not work with this hardware set up. If you want to use BASIC from ROM set the A15 Page Selection jumper to 0. A better solution though is to download a copy of mbasic or BBC Basic to CP/M, which then allows you to use the compact flash card for storage
