  Well I can at least boot from my rl02 cartridge on the Vax (thanks go
to Chris Torek and Joe Beckenbach for their responses).  Unluckily I am
unable to load the mini-fs to the r80 (141 Mbyte winchester disk, it and
the rl02 are controlled by the IDC controller on our 11/730).

PROBLEM:  I have a good r80 disk drive and IDC controller as best I can 
tell (passes all DEC diagnostics, and drive spins up fine); however, I
am unable to load unix on this disk.  I have tried loading the standard
distribution from tape, and in addition booted unix on the rl02 to try to
use the r80, with no success.  
  When I attempt to copy the mini-fs from tape to the r80 it gets error 
returns from the idc driver, i.e.

>>>L COPY
>>>S 2
From: ts(0,1)
To: rb(0,1)
idc error: (cyl,trk,sec)=(37,1,6) csr=413948b<R80,ECS0,ATN1,ATN0,ERR,DLT,OPI,CRDY,F2,F0,D??			
idc error: (cyl,trk,sec)=(37,1,26) csr=413948b<R80,ECS0,ATN1,ATN0,ERR,DLT,OPI,CRDY,F2,F0,D??			
idc error: (cyl,trk,sec)=(37,1,26) csr=413948b<R80,ECS0,ATN1,ATN0,ERR,DLT,OPI,CRDY,F2,F0,D??			
idc error: (cyl,trk,sec)=(37,1,26) csr=413948b<R80,ECS0,ATN1,ATN0,ERR,DLT,OPI,CRDY,F2,F0,D??			
idc error: (cyl,trk,sec)=(37,1,26) csr=413948b<R80,ECS0,ATN1,ATN0,ERR,DLT,OPI,CRDY,F2,F0,D??			
idc: recovered by retry
idc error: (cyl,trk,sec)=(37,1,15) csr=413948b<R80,ECS0,ATN1,ATN0,ERR,DLT,OPI,CRDY,F2,F0,D??			
idc error: (cyl,trk,sec)=(37,1,15) csr=413948b<R80,ECS0,ATN1,ATN0,ERR,DLT,OPI,CRDY,F2,F0,D??			
idc: recovered by retry
idc error: (cyl,trk,sec)=(37,1,4) csr=413948b<R80,ECS0,ATN1,ATN0,ERR,DLT,OPI,CRDY,F2,F0,D??			

etc. until I halt it.

On the other hand, when I was able to get the rl02 to boot an standalone 
minifs I had on it, I tried to do a newfs on the r80 with the following 
result...

# newfs /dev/rb0h rb80
rb0h: hard error sn110142 csr=41094c1<R80,ECS0,ERR,DLT,OPI,CRDY,IE,DRDY> ds=0
write error: 110142
wtfs:I/O error
#


I formatted the disk with the DEC formatter just prior to do all of this.  I
had attempted to use the Unix one, but of the two TU58 cassettes I had, the 
generic 4.2 cartridge didn't know about rb drives (only hp and up), while our 
old cassette accepted rb(0,0) however it filled in the sector/track/cylinder
defaults to all zero's, i.e.
    Device data: #cylinders=0, #tracks=0, #sectors=0
and while you can fill in the starting and ending track and cylinder number,
you don't get to set the sector values, so I didn't attempt this.  
  I'm considering trying to find somewhere else that I can make a cassette 
tape with known version of copy and format on it to test these again, but
that's all I can think of at this point.
  Anyways suggestions, solutions would be greatly appreciated.
