I have run 2.9.1 and 2.9-beta on a 11/73 system. The system contains:
11/73 processor, 1Mb PEBX ECC memory, DILOG 228 disk controller with
Fujitsu 160, DILOG 132 tape coupler with Cipher 891, Emulex CS01 (dh11)
in a MDB box. I have seen no problems of any type with this system.
The system runs with the DILOG 132 in TSV05 mode.  The only work
required on 2.9.1 was for the 22-bit address space (no UNIBUS map) and
for the TSV05 (it is almost a ts11).

So the question seems to be: Can you run with Fujitsu Eagles on a Q-bus
system?  If you are doing so would you please mail me information on
your system configuration, and any problems you may have encountered.
The Eagle is a very nice drive but can a Q-bus based system handle the
high transfer rate?

I will summerize the replies I get for the net.
