Thanks for the suggestions. BTW do you have any
doc for the Siemans
drives? A friend of mine just bought a couple of them. They were sold to
him as Shugart drives but they weren't. Now he's trying to figure out how
to use them in place of Shugarts.
Joe, the only thing that I could find on Siemens 8" drives is this
rather ancient bit from Fritz Chwolka in February '96. (I have a
hunch from the header that it dates back to Bill Blue's 'pnet' on
his (then) CTS.COM. I am unsure whether this will help your
friend or not since I don't know what model drive he has.

This is the only information I have...for the moment.
For other drive I have prints but not for the Siemens.
I hope this helps , instead I didn't read the original
letter.
I have some old Siemens CP/M-systems with 8"diskdrives
and 10MB Harddisk but they have an Shugart DS/DD 8" disk
inside.
