NetBSD/pmax kernel had a major glitch for raw device access like R/W of
tape or /sbin/dump of filesystem.  Please make sure to use 1.4.2 kernel
on your 3MAX+, or even better, to use DS5000 kernel made from -current.
Unfortunately, dev/scsipi/st.c would require a hand tuning to make any
tape devices useful on DECstations (the issue should be solved soon).

#define ST_IO_TIME      (3 * 60 * 1000)         /* 3 minutes */
#define ST_CTL_TIME     (30 * 1000)             /* 30 seconds */
#define ST_SPC_TIME     (2 * 60 * 60 * 1000)    /* 4 hours */
                        --- originally it was 4.

I have experiences of EXB-10e, 10 tape jukebox with EXB drive, it was
proven useful with Personal DECstation.

I have no helpful recommendation about backing softwares this mement.
