[pups] 2.11BSD disklabel-programm

hi there, maybe someone can help me installing 2.11BSD on a PDP-11/83. my problem: the standalone disklabel-programm stops when displaying the MSCP disk information. in the console ODT i write/see: BOOT MU0 Starting system from mu0 83Boot from tms(0,0,0) at 0174500 :tms(0,1) disklabel Disk? ra(0,0) d(isplay) D(efault) m(odify) w(rite) q(uit)? d type:MSCP disk:RD54 flags: bytes/sector: 512 sectors/reack: 17 tr and then it just stops, right after "tr", but the RUN led stays on. when i try to disklabel a RL02 disk i get invalid disk (for rl(0,1)) or a system stop (for rl(0,0) with RUN led off). i don´t know if this is a hardware (bus?) error, or maybe the tape is bad. the tapes i use are unused original dec TK50 tapes, i made several ones, because i thought it might be a tape error, but all tapes are the same. hardware: PDP-11/83, 4megs of ram, TK50, two RD54 (maxtor), two RL02 disks. qbus cards (top to bottom): *cpu (quad) *memory (quad) *controller for RL02 disks (quad) *controller for RD54 disks (double) *controller for TK50 (double) *network controller (double) i didn´t find a kind of terminator, but i didn´t change the order of the cards since i picked the box up. there are no empty slots between the cards, and i´m not sure if the Qbus need a special terminator. i made a TK50 boottape on my DECstation 5000/200. i got the software from the pups archive, and made the tape with the "maketape" program. any idea welcome. regards, --lothar
