[comp.sys.transputer] DMA

Does anyone have any experience in the transfer of data to the 
transputer from a IBM PC via DMA.  We a listing to do this but
are lacking three addresses, namely LinkInStatusReg, LinkOutStatusReg
and LinkDMAReg.  If anyone can help me with the above addresses (as
in where to find them, etc) or just with general experiences could
you contact me.           
Thanks in advance...

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.
