Your problem may be that the early versions of SCSI did not support SCSI bus parity. I believe (though I don't have a manual close at hand) that the 1542B at least can be jumpered to disable SCSI parity checking. Note that you'll have to do this for all devices connected to that SCSI bus, including any disk drives etc. phil -- ------------------------------------------------------------------------ Phil Sutherland Perth, Western Australia philsuth@DIALix.oz.au
