Are there any archived issues of _Processor_ from the 80's or early 90's, online anywhere?
I seem to recall it went through at least one major printing format change (from newsprint to cheap bound magazine or the other way around). It sometimes had articles but was mostly ads from second-hand minicomputer vendors. Most of what I remember was DEC-aftermarket of course, but there was also overlap with DG, IBM aftermarket, various office machines, and later PC-clones and Sun stuff.
