Has anyone fooled around with IOMEGA "Bernoulli Box" drives? I am wondering whether I can adapt a cheap 10 + 10 drive originally intended for the IBM PC to work with my Mac. There are at least two approaches I can think of: does the Bernoulli box use a ST506 or similarly standard controller, that could be replaced by a SCSI/ST506 board? Alternatively, is there any product out there that will let a IBM bus device be plugged into a generic SCSI port? And finally, will one of the generic Mac disk formatters (i.e. "Formats and partitions any brand disk") out there work with the Bernoulli box, assuming that one of these hardware approaches works, or will I need a Mac Bernouilli Box driver, or will I need to write my own driver? -- --mike bergman Massachusetts Microelectronics Center 75 North Drive, Westborough, MA 01581, USA +1 (508) 870-0312 UUCP: (...harvard)!m2c!bergman INTERNET: bergman@m2c.org

It is on my list of things to fool around with (perhaps a hard drive for my auld CP/M box - I actually had one running on it many years ago, somebody else marketed the design...). The controller board in this one has every appearance of using a SCSI interface (although the unit I hooked up to the CP/M box years ago had a SASI interface instead). I unfortunately have no documentation on the interface command set - the unit has a controller board for the PC (does not seem to work on an AT, haven't tried it with a PC yet) and associated software. Still, given a working configuration I don't see it being that difficult to adapt to some other system - assuming the interface from that system is not too difficult. -- Bill Swan bill@Summation.WA.COM Send postal address for info: Innocent but in prison in Washington State for 13.5 years: Ms. Debbie Runyan: incarcerated 01/1989, scheduled release 07/2002.

I don't have the literature handy, so I may be mistaken; nevertheless, I distinctly remember that they were SASI devices. Given that SCSI is rumored to be a superset of SASI, they may work. But I would be very surprised. =============================================================================== Roger Ivie 35 S 300 W Logan, Ut. 84321 (801) 752-8633 ===============================================================================

[...] This was true - the set I connected to my Alspa CP/M box long about '82 were SASI drives, but the PROMs in the set I have now are explicitly labelled "SCSI". None of which is very helpful to Mr.Bergman who asked the original question... -- Bill Swan bill@Summation.WA.COM Send postal address for info: Innocent but in prison in Washington State for 13.5 years: Ms. Debbie Runyan: incarcerated 01/1989, scheduled release 07/2002.

The original IOmega boxes were SASI interfaces, but IOmega changed to SCSI several years ago. The SASI interface is indeed the predecessor of SCSI, but they are not compatible. -- Philip E. Johnson UUCP: usenet!ingr!b3!sys_7a!phil MY words, VOICE: (205) 772-2497 MY opinion!

Here we use SCSI devices from SASI host adaptors (and vice versa) with great success. The SCSI bus is certainly a wild and improper superset of SASI, but the ancestry shows through quite strongly. -- John Woods, Charles River Data Systems, Framingham MA, (508) 626-1101 ...!decvax!frog!john, john@frog.UUCP, ...!mit-eddie!jfw, jfw@eddie.mit.edu Happiness is Planet Earth in your rear-view mirror. - Sam Hurt
