We have two System Industries STC tri-density tape drives (model 9700-53 
if I recall correctly) running on our Symmetry S81.  We interfaced them 
to the multibus using a non-standard Xylogics 472-902 tape controller 
and a Zetaco Pertec-STC converter box, both from Interscience Computer
Corporation.

The Xylogics tape controller is not the standard "off the shelf" version -
it has a special eprom (provided by Interscience) which must be at a certain 
revision level.  Also, we had to fiddle with the timing delays on the converter 
box to get it to work.  I forgot the exact details but I have them somewhere 
in my notes.

They've been working fine ever since.  We dump several gigabytes worth of 
data every week with no problem.  Feel free to call me for more details.

ps.  Our inbound dial-up links are screwed up right now due to the sudden 
     unexpected activation of the Defender system on our data switch so 
     I wouldn't trust UUCP mail to hacgate.  I've got someone working the 
     problem but I don't know how long it will take before our links are 
     back up.  I don't even know if this article will make it out.
