The SI9000 series are nice SMD controllers.  We had one on a CMI
interface on a VAX-11/750.  It made a 160MB Fujitsu drive look like 2
real RM03s (and would boot from the DR boot ROMs) and it made a
Fujitsu Eagle look like a fat RM05.  We had to patch DRDRIVER.EXE with
the geometry tables every time we upgraded the OS.  That one got to
VMS 4.6 and we froze it there.  All of our VMS 5 work was on 100% DEC
hardware.  The SI 9xxx box could accept multiple SMD drive interfaces
(3? 4?) and at least 2 host connections (we had one).

I know Systems Industries made Unibus and Qbus host cards too but I
never got the chance to play with them.

Looks like a fun box but I don't need another 11/34 and I live too
many states away.
