I would consider it very unlikely that it would work with any other
adapter.  The driver needs intimate information on the i/o ports,
memory areas and dma channels used by the adapter.  These are likely
to differ greatly between different adapters.  I would consider it unlikely
that anyone would clone the ST-01.

What I hve heard, the Adaptec adapters use dma.  The driver does not
support dma, as the ST-01 did not (and I did not have any documentation
on how to use the dma channels in sysV/386).  I have also heard that
technical documentation of the Adaptec adapter would be hard to obtain;
I haven't tried though.  (Using a dma-driven controller would probably
improve performance by several hundred percent from that obtained
with the ST-01 (under msdos even it performs quite well, though).

If there are no other criteria for selecting the controller and you
can't get any other controllers to work, the ST-01 costs something
like $50 (I don't know the price in the US).
