This address scheme may seem a bit strange but it is
identical to that used by IBM for their board and for the
National Instruments PC2A board and so ensures that the PC
ELITE card is absolutely compatible with these other, older
technology, boards.
NOTE 1: The IEEE input-output is done at the i/o address set
__________
by the DIP switches on the PC Elite board. The
above i/o map is relative to the base address set by
these switches.
The I/O Address Base Address.
___________________________
The PC ELITE IEEE board i/o address can be set to reside
at one of 7 base addresses in the PC using the I/O Address DIP
switches at the lower left hand corner of the board. The factory
set address is 02E1H. See Chapter 2 Figure 2-1. The 7210 TLC
register map is relative to the i/o base address set by the address
DIP switches.
