Has anybody out there used one of the new FLOPTICAL 3-1/2" drives on a
Mac? Specifically, I'm looking at the Insite Peripherals Floptical SCSI drive
that I'd be attaching to my IIcx that's running A/UX 1.1.
I'd like to hear from anybody that's got one of those up and running, whether its
under Mac OS or A/UX.

I have a COSMOS 600mb from RACET optical read/write unit for testing.
It works OK both under A/UX and MacOS. If you want to create A/UX
partitions, first create HFS ones, and change the type with 'dp' from
the A/UX side. The media conforms to ISO, and has a capacity of 298Mb
formatted on two-sides.
The access time is about 50ms, not bad, not good... I don't know who sells
these units in US.

These alignment markings allow them to pack a *HUGE* number of tracks on a 3.5" floppy, and hence cram a *HUGE* (20 MB) amount of data onto a floppy. The prices I've seen for the drives (in recent BYTE Magazine issues) are ~$500 U.S, with the cost of the Floptical disks being ~$7 - $12 U.S. Better still, the access times are quoted as being (working from memory) around 65 ms. These things would not only make great BACKUP devices, but are practical as low-cost removable hard-drives. So, to reiterate my original question: has anybody got one of these up and running on a MAC under either MacOS or A/UX? --Ryan --------------------------------------------------------------------------- ryan@amc-vlsi.uucp | Ryan Jorgenson ryan@amc-vlsi.ucalgary.ca | The Alberta Microelectronic Centre | Calgary, Alberta Canada
