Sorry for not providing the right info - basically I have a pioneer cd rom drive which i bought from ebay this week.
I am connecting it to my amiga 600 using a squirrel SCSI interface which has a PCMCIA card.
The brand name on the user manual is "Squirrel SCSI" by Hisoft -
The brand name on the installation disk is "Power cd rom"
I have never used a cdrom with an amiga before and just wrongly thought that the PCO:

? reference was refering to the cd rom -
Is there any extra information I need to supply to help get this drive working.
