I wouldn't say a SCSI tape controller is useless, always fun for
installing software from tape just for the heck of it. But that's
beside the point for now.

Anyway, yes it would be still worth dumping the CDU-710/T CSR decode
PAL fuse map just for reference and to confirm that are earlier
attempts are reverse engineering it were correct, and use that as the
starting point for a 710/M or 710/TM PAL in the absence of one of
those to also dump.
