[comp.sys.mac] MAC-XL expanssion port

floyd@humu.UUCP (Robert W. Floyd) (01/22/87)

We have a MAC-XL (lisa) with a parallel expansion port.  We woul'd like to
connect the Lisa through the expansion port to a HP-IB (IEEE 488) bus, but
our information on the parallel port is limited.  We would like to here from anyone who might have done this, or from any one who has enought information about the parallel port for us to do it ourselves.  In particular, we would like
information about the parallel interface chips on the board and their addresses in the Lisa environment.

Thanks'
