SCSI switch settings

Sun Jul 1 23:15:32 AEST 1990

I just got a Wangtek 60 MByte (QIC-24) model 5099 and a Wren IV 94171-376
in a third party expansion box for a Sun 3/50 (and no documentation).  Can
anyone tell me the proper id switch settings for these two? Would the
settings be different if used in conjunction with an existing 1325 disk on
an Adeptek 400 in a Sun shoebox.  Do I have to alter the software? (Now
running 3.4 but probably moving to 4.1 soon).
