The KRQ50 version of the rrd40 is not scsi it is serial driven (lms
?). The rrd40 are also really slow less then 1x speed drives. Unless
you want it for shits and giggles I wouldn't recommend using one. It
would be quicker to use a pc running simh to copy files across when
you need them (not as fun though). Also if you do find the right rrd40
it probably won't come with caddies or cables.
