MicroVAX II - TK50 problem

The saga continues... Got the system running finally, but now I can't get the TK50 tape drive to work. Have checked the cabling, reseated everything, and even tried a different TQK50 controller. Have tried the following from VMS 5.1: $ RUN SYS$SYSTEM:SYSGEN SYSGEN> SET NOAUTOCONFIG 0 SYSGEN> AUTOCONFIGURE ALL/SELECT=(PT) (at this point the system hangs... same if I omit the /SELECT, and the only way I can get out of it is to halt the system from the console.) Here's what the system is showing: Welcome to VAX/VMS version V5.1 Last interactive login on Thursday, 10-MAR-2005 10:27 $ SHOW DEV Device Device Error Volume Free Trans Mnt Name Status Count Label Blocks Count Cnt DUA0: Mounted 0 VMSRL5 184419 94 1 Device Device Error Name Status Count OPA0: Online 0 TXA0: Online 8 TXA1: Online 0 TXA2: Online 0 TXA3: Online 0 TXA4: Online 0 TXA5: Online 0 TXA6: Online 0 TXA7: Online 0 Device Device Error Name Status Count PUA0: Online 1 Thanks in advance!
