Thanks Michael! I did read through those but I'm still getting used to
operating the 6800 and am still a bit confused. If I want to confine the
program to a certain address range, say $ to $, is the most significant
byte of $, 0? As well as least? And then 1 and 1 for the hi

Hi, Mike. See further below where I mention Bart Lagerweij's
SCSI Tool Utility (an MSDOS program) with the drive connected
to a PC.

That's the transport; but what are the shortcomings of the medium itself?
FWIW, I've got at least one DDS drive with rubber parts that have turned
to goo.

I know it's true for the full height. I've had dozens of dead ones

Now, those would be unusual! Mostly because the Syquest SparQ wsa a

Then perhaps that's what they are. They looked like tapes when I
looked at the business edge of the cartridge, that's why I called them
tapes. But

Thanks for posting that the KT-11B documentation is available.
Does anyone know if schematics for it were included in the auction?
The flip chip board complement for it is in the posted document but nothing
else.
If the schematics are available, are there plans to get onto bitsavers?
