Nope -- it emulates RP02 drives. Jeff, the original poster, and I got
the emulex card to work with each of the 5300 drives (so we know all the
hardware involved works). We cannot get the Dilog DU202 controller to format 
a 5300, because we do not know the format of the header table required
in memory at the commencement of formnatting. The manual does not tell the
format for the sector size byte, or the overall organization of the header
table. Dilog won't tell us either, only offering to sell a disk that has a 
format program on it for $250 (more than the whole 80meg SMD drive is worth,
if you ask me). 

So, we still ask to hear from anyone with experience (or at this point,
anyone willing to sell an SMD controller an SMD controller with good doc's 
and/or formatting software useable with a Kennedy 5300 3-platter SMD drive). 

Thanks a bunch,
Richard Chapman 

There has been a thread about what SC02 emulates. Here's my $0.02:

As far as I remember, there's no such beast as SC02. 
There are SC02/A and SC02/B, the former emulating RK06/07,
the latter RP02/03. I ran into this with my SC03's.

From the Emulex PDP/LSI Disk Controllers student guide:

                        SC02/C 

(RK06/RK07 Compatible) Disk controller Technical Manual

Drives Supported:

Cyl   Trk  Sec  Configurations
700    5    35  5, 5b, 15

Unfortunately, It doesn't tell you how to set the configurations for this 
controller. :-(
