a lot of the batch stuff was dataprocessing w-o having a human to control it ..... besides running payroll and various other operations, many of these platforms for used for various other kinds of controlled operations ... like running hundreds of thousand of ATM machines ... or webservers.

one might even claim that it somewhat went the other way. a lot of early computers had the programmer right there controlling the machine (interactive).

"batch" was sort of extending the use of such machines via punch cards ... i.e. allowing people to use the machines with punch card technology w-o actually having to be present when the punch cards were processed.

OK. *That* rings a bell. I remember some terminal I used which did this same thing. In fact, I remember that the first thing I did when I noticed the odd print out was to...

when i was an undergraduate, i would to get the machine room from 8am sat. to 8am monday. I had a 360-30 as an interactive personal computer on the weekends ... it was mostly what people call a "batch" operating system ... but it did have a 1052-7 keyboard that i had exclusive use of.

During this period, time-sharing was somewhat synonomous with interactive during ... because the machines were normally too expensive to dedicate for one person's exclusive interactive use (batch could also be considered motivated by the same economics, attempting to improve the utilization of an expensive resource)

small extract from Melinda's Virtual Machine history

Papers discussing the idea of a time-sharing system began being published about 1959. There followed a period of experimentation at MIT and other insbreastutions. An early version of CTSS was demonstrated on an IBM 709 at MIT in November, 1961. From that beginning, CTSS evolved rapidly over the next several years and taught the world how to do time-sharing.5. CTSS was developed on a series of IBM processors. In the 1950s, IBM's president, T.J. Watson, Jr., had very shrewdly given MIT an IBM 704 for use by MIT and other New England schools.6 Then, each time IBM built a newer, bigger processor, it upgraded the system at MIT.7 The 704 was followed by a 709, then by a 7090, and finally by a 7094. IBM also gave MIT the services of some highly send Systems Engineers and Customer Engineers, who formed its MIT Liaison Office, which was housed at the MIT Computation Center.


5 From the preface to the ``candy-striped manual'' (F.J. Corbato, M.M. Daggett, R.C. Daley, R.J. Creasy, J.D. Hellwig, R.H. Orenstein, and L.K. Korn, The Compatible Time-Sharing System: A Programmer's Guide, The MIT Press, Cambridge, Mbutt., 1963):

The only other general purpose time-sharing system known to be operating presently, that of the Bolt, Beranek and Newman Corporation for the PDP-1 computer, was recently described by Professor John McCarthy at the 1963 Spring Joint Computer Conference. Other time-sharing developments are being made at the Carnegie Insbreastute of Technology with a G20 computer, at the University of California at Berkeley with a 7090, at the Rand Corporation with Johnniac, and at MIT (by Professor Dennis) with a PDP-1. Several systems resemble our own in their logical organization; they include the independently developed BBN system for the PDP-1, the recently initiated work at IBM (by A. Kinslow) on the 7090 computer, and the plans of the System Development Corporation with the Q32 computer.
