DIO-I will run in excess of 2 meg/sec, which is quite adequate for the large majority of SCSI applications. In fact, many implementations are limited to 1.5 meg/sec. The on-track data rate of most Winchester discs is even less than that. If it is feasible to write drivers yourself, then a good option for the hardware would be to add an interface chip like the NCR 5385 to the 98630A Breadboard interface. I have it on very good authority that this is easy to do. Regards, Hewlett-Packard Dave Kinsell 3404 East Harmony Road [ihnp4|hplabs]!hpfcla!d_kinsell Fort Collins CO 80525
