I'm trying to get an old M4 9905 tape drive running with my PDP-11/73's
Pertec interface and I'm not having a ton of luck. Currently attempting
to boot from known-good media spins the reels a bit and then gives me an
"Error 21 - Drive Error" from the 11.
I want to check that the drive is configured correctly. There are
evidently settings that can be tweaked by running internal diagnostic
programs from the front panel, but I don't know what the codes are. I
haven't had much luck finding a manual on the 'net (Bitsavers has
manuals for the 9914, which is similar but not similar enough that the
diagnostic programs are the same.)
Anyone have a manual or a diagnostic listing for this drive?
Thanks,
Josh
