The drive roller was a mess, black gunk getting onto the tape casesm
fortunately not the tape itself, I cleaned it up a bit and it now seems
to turn the tape easier. I'll try cleaning the head tomorrow

I'd say the tapes match the machine, the tapes are marked SunOS 3.2 68010
Export (boot format) and the one time I got SunOS started of the HDD it
was the same version exactly. I actually have the HDD backups on 1/2"
tape, but none of them are bootable. It is possible the tapes have died,
but I heard of the old sysadmin who operated the machine that the tape
drive was "not quite right".
