Yes.  As it turns out, IBM decided the standard Exabyte PROM was a bit
crufty so they replaced it with their own.  A standard SCSI 8mm drive
will therefore not work with the RS/6000.  The two options 3rd-party
vendors have are: to write a device driver for their drive, or to make
their tape drive work like IBM's.

I went through all the trials of trying to get a standard 8mm drive to
work only to find out the information above.  At least you didn't buy
the drive...

I currently have a CCG 8mm drive and it is working well (they took the
second approach).
