TOPS-10 is an operating system for Digital Equipment Corporation's PDP-10 family of mainframe computers (including the DECsystem-10 and DECSYSTEM-20 product lines). TOPS-10 was first released in 1970 and the last release was in 1988.
LCM+L currently has two TOPS-10 systems available on-line:
|dec-10||DECSYSTEM-2065 / KL10||TOPS-10 version 7.04|
|ki587||DECsystem-1090 / KI10||TOPS-10 version 6.03A|
Apply for a user account on one of LCM+L's TOPS-10 systems with the Request a Login form. Check the box “Tops-10 v7.04 (DECSYSTEM-2065)” for an account on dec-10. For an account on ki587, write a memo in the box “(Optional) Please describe your interest in these systems:”. After completing and submitting the form, within a few days you will receive e-mail from LCM+L with your project-programmer number (PPN, TOPS-10 user ID) and initial password.
Connect to the system by opening a Secure Shell session with the destination for your host:
On ki587, after the log-in message is displayed, press the Enter key once or twice to display the command prompt
LOGIN command to start your session.
Command format: TOPS-10 commands are one to six characters long. At the command prompt
., type the command string or a unique prefix followed by command arguments if any, then press the Enter key to execute the command. In version 7.04 commands are case-insensitive; in version 6.3 all entered command text is automatically converted to upper case.
File name format: TOPS-10 files are identified with a file name from one to six characters long followed by a period (
.) and a zero to three character file extension. Many commands allow wildcard characters
* (matches any zero or more characters) and
? (matches zero or any one character) in file name arguments to operate multiple files.
Files with standard extensions are given special treatment by some commands.
