Some applications for SITS. Some of these were taken from the ITS file SITS; HELP 2, or guessed from this list: #1

• SYSSPR, the System Sphere. System job that is the first to be started by SITS.
• SLOGO, SITS 11LOGO. This is the main application, really..
• DDT, login shell for advanced users.
• INQUIR, for entering new users into the system.
• FNT, for loading fonts.
• DIRED, directory editor.
• SPEEK, SITS PEEK.
• OS, possibly output spy.
• SLISP, 11LISP ported to SITS.
• TECO, text editor.
• TINTE, another text editor.
• MAIL.
• ITS, Datapoint simulator and file transfer.
• FPSW, Spacewar?
• JOTTO, word game.

Tools for the 3500:

• STUFER, to stuff the LSI-11.
• LSIFIL
• LSIDBL
• LSIEND

So far I figured out these are the hardware devices SITS expects. They are configured for SIMH in the file hardware.simh.

• 11/45 CPU with MMU
• 128K memory
• EAE, extended arithmetic element
• KW11P programmable clock
• PC11 paper tape
• DC11, 2 terminal lines
• DHQ11, 16 terminal lines
• RF11 fixed disk
• RK11 movable disks
• "NG", Tom Knight's point plotting displays
• "TV", Ron Lebel's raster displays

files/11logo contain three .disk files. They appear to be images from SITS disks. Timestamps are from May 1978.
