then you either need a mac compatible controller card wint a 50 an a 68 port, or
i think better,
you use a pc store (whith a technician, of course) simply to let copy the data on a, for example, usb harddisk or stick.
mac and scsi, once standard on a mac, but that was really ages ago.
the pc store do not need a mac or the ability to interprete the filesysytem in order to clone the partitions.
but there are many more pc-scsi controller cards out there than mac compatible.
and ist is not so easy to correct setup a scsi chain.
so buy the time from someone, who do not have to think about such a thing as get data back from an slightly older standard.
i hope, the data is readable, because its not very good for the integrity of the data, if it is stored a very long time.
