| | TCC NEWSLETTER -- VOLUME 3, NUMBER 5 (October 1977). |
| | An ISML package exists for DECsystem 10's and 20's, and we'll probably replace the IBM 360/370 version we wow have instead of attempting to convert it. | | | Anyone who depends heavily upon this set of subroutines, or specific routines within it should make their needs known as soon as possible so that a conversion priority, if needed, can re established. | | | Users of this package who have immediate needs should also pay us a visit... |

| | Larry Osterman's WebLog : Hacking the Decsystem 20 |
| | For a while in the mid 80's, a Decsystem 20 was our email machine at Microsoft -- in the Windows group, at least. | | | Back when I was in college, we did all our class work on Decsystem 20's running TOPS-20. | | | I've got to say that the dec20 is STILL my favorite processor architecture, even if it did have its quirks (like a 36 bit word size). |

| | THE DECSYSTEM-20 AT COLUMBIA UNIVERSITY |
| | DECSYSTEM 20 Assembly Language Programming Guide (Columbia U): | | | The DEC-20, with its PDP-11/40 front end, was designed on the assumption that terminal input comes directly from people sitting at keyboards typing with their fingers at a relatively slow rate -- maybe 10 characters per second, tops -- whereas large amounts of sustained output can be sent from the computer to the screen. | | | Rather than use the PC's floppies to store mainframe files, users were doing most of their file creation and manipulation on the PC, and sending the results to the mainframe for archiving and sharing. |

| | Open the second door from the left side of the DECSYSTEM-20, directly under the DECSYSTEM-20 control panel, to access the front-end switches. | | | Perform steps 10 through 21 to load and start the TOPS-20 monitor. | | | Error: If the system does not print a heading similar to one of those above, be sure that the correct floppy disks are mounted in the proper drives, then return to Step 12. |

| | Page 10 2.3 User-oriented Design Philosophy A piece of system design "philosophy" had emerged at BBN and among some of the ARPA research sites that was to have a large impact on the overall feel of TENEX and, ultimately, TOPS-20. | | | At the time, we called this "human engineering" -- we wanted the system to be easy to learn and easy to use, and we wanted the system to take care of as many grungy details as possible so that the programmer or user did not have to deal with them. | | | Page 18 Around this same time, the "Super Foonly" project was in progress in the AI lab at Stanford. |

| | Their larger PDP-10 cousins, which used a 36-bit architecture, were aimed at data-processing centers instead, eventually being sold as the DECsystem 10 and 20. | | | PDP-11 machines started in the market essentially as upscale PDP-8s, but as improvements to integrated circuits continued, they eventually were packaged in cases no larger than a modern PC. | | | The PDP-11 systems supported several operating systems of the day, including Bell Labs' new UNIX operating system as well as DEC's RSX and RSTS. |

| | The soul of an old machine - Clive Dawson's story of the DEC-10 |
| | I liked the DEC 10 better than the DEC 20. | | | I can't begin to count the hours I spent on that system--well over 10,000 connect hours-- developing software for it, fixing bugs, and helping users. | | | Since then, I had spent four rather painful years doing graduate work on a CDC 6600 system for which I had to learn how to keypunch again. |
