I updated the page, and found out that there is a Datum 4091EC disk 
controller in slot 12 optioned for a Diablo 30.  I was wondering if 
anyone has any info on those as well as the Datum card.  Is there a 
similar effort to get an emulator for the Diablo drive as there is for 
the RL02?  From the Diablo info on Bitsavers it says that Datum used the 
5440 drives, which would be similar to the RL02, Western Dynex, and 
Microdata 7000 Marathon drives, all of which used the top loading 2.5 
and 5mb cartridges.

I know the Alto guys all are using the front loading Diablo drives, and 
wondered if that is similar?  Lots to learn about the system.
