Desperate Plea: Digital DNARD Boot Problem

[Jon]

I bought a grey box at the MIT flea that turned out to be a pretty neat
piece of old equipment know as a Digital DNARD (Rev. 4).  While trying to 
update the firmware managed to render the DNARD unusable. 

Does anyone know how I could get in touch with the guy in the garage who
was selling these or where I could get the September, 1998 version of the
firmware?

Thanks,
Jon

P.S. I have done all the normal google searches, but every time I get close
to finding the correct firmware I hit dead links.
