Brief notes on installing SITS on SIMH.

Introduction

  • RUG is a DDT-like memory resident debugger, like ITS' non-time-sharing DDT. It can also handle a variety of media for reading and writing files.
  • SALV is the disk salvager, same as in ITS.
  • SYSSPR is the system sphere, the first program run by SITS.
  • DDT is the user interface command processor, like DDT/HACTRN in ITS.
  • INQUIR handles a user database, like on ITS.
  • FNT is a system program which loads fonts for use on the TV displays.

Prepare media

Have these absolute loader paper tapes ready:

  • SALV
  • RUG

Run RUG; PUNCH on ITS to read these PALX binaries and punch out paper tapes:

  • SITS BIN
  • SYSSPR BIN
  • DDT BIN

PUNCH will divide the output in a series of tapes. It will valret in NEWBLK; continue with $P when a new tape has been mounted.

PUCH will valret at EDONE when finished.

Format disks

Boot the SALV paper tape.

SALV will print a * prompt. For each disk pack, type nI to format the pack.

Install system files

Boot the RUG paper tape.

RUG will print a * prompt. First, type $^D to copy RUG to disk.

Load SITS, SYSSPR, and DDT from paper tape, and save them to disk. For each program type $L P: to load from tape. RUG will halt when it's time to mount the next tape, and return to the * prompt after the last tape. Type $Y to save the program to disk.

RUG can also load from a serial line with $L T: or over the Rubin 10-11 interface with $L M:, but this requires running ITS on the other end.

Transcripts

This shows SALV used to format a disk. Other disks are done similarly, but only the first needs to be a "Rug disk".
