I am one of the few lucky DSS-1 owners who was able to purchase a DSS-1 with
expanded memory and a SCSI interface. This upgrade also speeds the internal
disk system load time from 45 seconds to 22 seconds. Unfortunately, this upgrade
is no longer available anywhere. However, here are some resources you may find
useful if you are also the lucky owner of one of there rare beasts.

I hope in the near future to start making available disk files that make use of the
expanded DSS-1 expanded memory. I have only the factory disk now which
makes use of 2 banks of memory. Stay tuned.
