There were many things that IBM came out with but dropped. One of the 
best op systems for micros was OS/2, a true multiusers system. I used it 
for a few years and it was far superior to the MS offerings at the tie, 
but IBM dropped it.  In the same misguided way they chose MSDos rather 
than CP/M for there micro computers.
