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? --Chuck
