Yup, the Drivetec, later Kodak (after Drivetec's bankruptcy). The positioner was pretty clever--two steppers connected by a lever arm...

It was the Kaypro Robie that had those weird 2.6MB 192 TPI 5.25" floppy drives, right? That thing was such a roaring success I'd say...

Oh, I got it. I just didn't really think the support for your argument against them was entirely sound, because the only forum you...

The *really* important thing you need to understand about the 6845 is what it *doesn’t* do. The chip generates sync/timing signals...
