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. thanks jim
