Getbyte error on Tape-Boot

[horke at buchonia.rhoen.in-berlin.de]

I wanted to boot Sun OS from tape with an Archive-Streamer (2150S) to a
3/50, but there is an error when I try to boot st(0,0,0) :

st: error, sense key = 5 error = 0
getbyte error, target never set REQ
getbyte error, phase mismatch
invalid status msg = FFFFFFFF
st: error, sense key = 6 erroro = 0

Nearly the same error occurs, when I forgot to install the resistors on
the HD, but the Tape works okay if the OS is bootet via HD.

 Can somebody help me ?
