USER MANUAL

ADDRESS SELECTION

The IOD-144 Input/Output Card occupies 24 bytes of I/O space. The card base address can be selected anywhere within an I/O address range 000-3FF hex. If all 144 bits are to be used in an AT-class computer, the base address can be set anywhere within the address range hex 100-390 (except 1F0 through 1F8). If to be used in an XT-class computer, the starting address can be as above except the lowest starting address is 200 hex.

However two installed options can not share the same address. If in doubt where to assign the base address of the IOD-144, refer to the tables below and consult the FINDBASE program on the utility diskette.
