IBM DCS/DCOS--how common?

[Chuck Guzis]

This talk of old tape brings up a question that I wanted to ask the list.

I've run into some tapes that say they were prepared on the IBM DCS
setup (7044-coupled-to-7094) running DCOS.

I confess to never having run into the 7044 in real life--it always
seemed like an odd machine--basically, a 7094 Jr.

There couldn't have been very many DCS setups, am I correct?
