Thank you for the input, that would be a good consideration also, for a
slightly different experiment (there are several variations I am
considering).
I am not sure it will fit with the current experiment: the driver in the
old MacOS7 (guest system under Baslisk II) is a SCSI driver for the
printer, so thought it will be simplest to have the device as a SCSI in the
host linux system.
