Thanks for the pointer!
But I doubt that I will be able to read the drive
with a Xylogics 451, for example. According to the Xylogics manual, there
are two supported disk formats, the 440 format and the 450 format. They
differ in the header field, the SYNC byte is $98 resp. $CC, and header
byte 2 additionally contains a "sector" field. The format and sector size
is configured by several PROMs. Not to speak from other controllers...
Any way, I will give it a try.
