Great to know that dua9 bit.

My controller is a revision F thing with 3 data cable connectors plus
the main bus connector plus the terminal i/o connector (I think that is
what they all are).  If the third data cable connector is not for a 3rd
drive, what might it be for?  I have no docs on the critter (as usual).

OK.  My one drive that I have that came with it (a 300mb maxtor thing)
must be formatted correctly, since it ran up an ultrix tape.  I have
now loaded Quasijarus 4.3 BSD on it for some testing, and it runs OK,
but I can't decipher what are the correct boot blocks to use from
the 4.3 era.  The raboot did not work, and likewise the kraboot, but,
I originally had a NetBSD-1.4.3 boot block on it and that worked the
first time.  I may try that again.  It will boot off tape, though and
then bring up the main system, in a pinch.  The drives come up via
dmesg as ra80 drives, so I was thinking the raboot would work, but
not quite.  Oh, well.....

My spare esdi drives (Sun things ... Micropolis 1355's) will probably
need dilog formatting, I am assuming?

Thanks
