-> This echo is for the enjoyment of "retrocomputing".  Any computer system,   
   -> be it a mainframe all the way down to a tiny T/S 1000, is on-topic here   
   -> as long as it is not currently being manufactured.  Hardware and software   
   -> discussions are also on-topic.   
      
   You bring up a good point.  I had an instructor in the 80's I knew that   
   kept a main frame in his closet in his room.  He also had 2-3 personal   
   computers there.  A Commodore 128 and a Zenith PC for sure....  I used   
   to enjoy playing on his Commodore 128.  Especially at the time, I had   
   the Commodore 64, and knew so little about the 128.  I especially loved   
   using CP/M mode!  The mainframe he had in the closet, if I remember   
   correctly basically ran on CP/M as well.  For the longest time, I always   
   thought one day, when I got my own place, I'd get me a main frame, and   
   setup terminals all throughout the entire house... Have each room wired   
   for serial ports to connect terminals to it...  Then things changed...   
   Now, what I had wanted to do with the mainframe can be done with my   
   Raspberry Pi and wifi or wireless access points connected to the wifi!   
   Gone are the days of the old mainframes...  True, there are still places   
   that use AS/400's, but not the same thing... Few companies refusing to   
   modernize.... A lot of companies are also using "Thin Clients", which   
   have potential.
