Looking for DEC XXDP TU58 images

Unfortunately I can't get past that solid-on diagnostic LED.  I had 
hoped that it might have been re-purposed in a later rev level :-)

Got all the ZRQ* binaries downloaded via simulated TU58 and they hang - 
funnily enough the old-rev ZRQA that I have on floppy reports the 
controller there and passes interrupt test before failing with 'no 
drive'.  I can also access the CSR using ODT. Not much more I can do 
without more tech data so I guess I am still looking for an MFM controller!

I've been nursing a painful tooth infection so I might have missed 
something!
