Does anyone have a driver or utility that will let me read a floppy made
on an Altos 586 (tar or mount format) on an IBM-AT running the latest version
of SCO's XENIX?
This would save me from transferring 30 Meg of data with Kermit, so I'd be
willing to pay a reasonable price.
The Altos writes DSDD 96tpi disks, so it is theoretically possible. I'm not
interested in how to go about writing a program to do it. I want to get a
finished program.
Anybody got one?

I routinely transfer floppies between my Altos 586, 3b2/300 and AT running SCO Xenix SysV. The trick on the AT is to use the /dev/fd096ds9 entry. I use cpio more than tar, but they both work. A trick on cpio is to use the B option when writting out the floppy on the Altos/3b2 to read on the AT. Also, *always* use the c option on cpio. Ex: on Altos-- find /usr/src/sysV -print | cpio -ocB > /dev/fd0 on AT -- cpio -icdB < /dev/fd096ds9 -- .. that's the biz, sweetheart...

If the disks are w~hat I think, it's not only possible, it's very easy. Xenix's device driver for the floppy can handle any combination of 1 or 2 sides, 40 or 80 tracks, 8, 9 or 15 sectors per track. They have devices for all these. In your case, you want /dev/rfd096ds9 or rfd096ds8 depending on how many sectors per track. I use the 96ds9 device for all my backup and TAR work. It's 720K but it works just fine on cheap floppies, so you don't have to pay 5 times the price for 1.2 meg ones. Now, somebody should write a 720K DOS device driver for the AT! -- Brad Templeton, Looking Glass Software Ltd. - Waterloo, Ontario 519/884-7473

If the disk is a 96tpi format with 9 sectors/tk or 15/sectors/tk you should be able to just read it with the proper device. As far as I can tell you could also read 8 sectors/tk, but I hope nobody uses it. I have had best luck with cpio disks, using "oBc" options to create and "iBcdml" to read (yes I know "l" isn't supposed to work with"i", but it seems to). -- -bill davidsen ihnp4!seismo!rochester!steinmetz!--\ \ unirot ------------->---> crdos1!davidsen chinet ------/ sixhub ---------------------/ (davidsen@ge-crd.ARPA) "Stupidity, like virtue, is its own reward"
