Looking for SCSI / Floppy software for Sun Workstations:
We are considering putting together a system for manufacturing software.
We need to make custom packages for each sales order. We need to support
several media including:
Sun Cartridges
9 track 1600bpi 1/2" tar tapes
IBM PC MS-DOS 5 1/4" DS DD floppies
IBM PC MS-DOS 5 1/4" High Density floppies
IBM PC Xenix 5 1/4" High Density floppies
Microware's OS-9 5 1/4" floppies (variety of formats)
Microware's OS-9 3 1/2" floppies (variety of formats)
Others in the future.
The cartridges and 9 track tape is easily do able off the shelf
(thought I would like to drive the 9 track tape from SCSI if possible,
but because of ease of implementation, we will probably use a regular
tape controller on the VMEbus).
The difficulty is connecting the floppies to the SUN. Sun Consulting
offers a device driver and utility package that lets one read, write
format a PC DOS floppy. Unfortunatly it does not work with any version
of PC-DOS greater than 2.xx and you need an ATT source license for Unix to
get the source for the package.
So I am looking for something in the public domain for working with floppy
disks connected to a Sun via the SCSI bus.
I would like to have control over the various floppy physical formats
as well as the file system on the floppy.

OMTI, DSI, and Adaptec all make SCSI controllers with provisions for
floppy disk drives. You'll be on your own for software as far as I
can tell. One DSI controller I have on hand uses extensions to the
SCSI protocol to set up floppy formats pre-established for the board,
but the OMTI product is much more flexible. I think it's a 5000
series product.

Thanks, for the hardware pointers. The big issue is finding software
drivers for the Sun. Or if someone has done something like this
(have one computer that can generate a variety of floppy formats and operating
system file systems) on another computer (IBM PC running Unix?), please
let me know.
