- I can add some subjective comments from my experience with the NCR
- version of the B20. The application software was indeed as good or
- better than anything available on a PC at the time. It was also
- possible to buy user terminals for the machine to form a work cluster.
- The terminals shared the hard drive of the main machine, but I don't
- know if they used their own CPU or if CTOS multitasked. In any event,
- both the hardware and CTOS were very well crafted.
-
- On the other hand, the machine was quite expensive ($20,000 sticks in
- my mind) and the yearly support contract cost more than a new PC. You
- needed the support contract because the documentation assumed that the
- reader had cement for brains and if CTOS decided that it didn't like
- you, calling NCR was almost your only hope. Sometimes you were lucky
- enough to talk to someone who knew more than the location of the power
- switch. In all fairness to CTOS, almost all of the problems were
- caused by botched installation disks.
-
- The worst problem was that CTOS was a real operating system, with user
- names, security, logging (lots of logging), and everything else you
- would expect. Unfortunately, the poor little 8086 (later 80186 if
- memory serves) just wasn't equal to the challenge. The machine spent
- most of its time servicing the considerable needs of the operating
- system, and not much capacity was left for the operator. I guess it
- would be somewhat like watching an XT run Windows (assuming that it
- would). It would be fun to see CTOS running on a modern processor.
