[Coco] Sardis Technologies DMC "No-Halt" Floppy Controller

Good news here...I purchased one of those controllers from him in 1990.  I
also bought the schematics for it which I can put my hands on as I know
right where they are located.  If he is ok with it, I can prepare them and
send/upload wherever is needed.  An image of the driver disk would be really
good too.

Hey everyone,

I e-Mailed David Wiens of Sardis Technologies (email below) and there is a
chance he may release the DMC Controller info to the community. I dunno what
we as a community can do to encourage this, but this could be some good news
if he does so.

Sardis Technologies still has a website, as he is still in business working
with Microcontroller Software and Hardware Design.
