If you are using a B008 board, the addresses are:

boardbase + $00  -  input data register
boardbase + $01  -  output data register
boardbase + $02  -  input status register
boardbase + $03  -  output status register
boardbase + $10  -  reset register (write only)
boardbase + $11  -  analyze register (write only)
boardbase + $10  -  error location (read only)
boardbase + $12  -  DMA request register
boardbase + $13  -  interrupt control register

where boardbase = $150, $200 or $300 depending on
the switch settings.
