Okay, this could be a cause. We know the Tandon drives are rare. In the
first time Commodore selled more Micropolis and MPI drives. Later they used
Matsushita drives with the same code as Tandon drives. At this time no more
6530 for Tandon drives are produced. They used the 6530 for Micropolis with
an additional eprom.

That's an nice question. Did a 6530 for Tandon drives (901884-01) work in a
8250LP or a 8296-D?

That's bad ... 8-(

I've only see 901885-04 (Microplis drives with DOS 2.7). Did anyone find an
other 6530 on this adapter?
