Brief notes on installing SITS on SIMH.

Introduction

SITS is cross-assembled from ITS, using the PALX assembler. These are the major components:

  • SITS is the kernel.
  • 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.

Optionally, set cpu idle may be used to reduce host CPU usage.

Assembling from source code

Login to ITS and assemble — at a minimum — RUG, SALV, SITS, SYSSPR, DDT, and FNT. RUG is the file AR in the RUG directory. All the other programs are in the SITS directory. Then take the BIN files and punch them to paper tape, or save them to magnetic tape.

This is a transcript of logging in, and then assembling RUG and SITS. The rest of the programs are processed just like SITS.

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:

  • SALV BIN
  • SITS BIN
  • SYSSPR BIN
  • DDT BIN
  • FNT 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.

PUNCH will valret at EDONE when finished.

This transcript shows how to start PUNCH in the RUG directory, and then punch out SITS BIN in the RUG format. The first .VAL messages is when PUNCH stops for the user to mount a new paper tape. This is optional. The last .VAL is when PUNCH is done, and can be killed.

Format disks

Boot the SALV paper tape.

SALV will print a * prompt. For each of the four disk packs, type nI to format the pack. Only the first needs to be a "Rug disk".

Install system files

Boot the RUG paper tape.

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

Load SALV, SITS, SYSSPR, DDT, and FNT 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. The files are written to the "." directory on disk 0. Save SALV as the name DAZZEL. This is the default name for loading a file from RUG.

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.

Start SITS

Boot the RUG paper tape. (If RUG is already in memory, start it from 157000.) When started, RUG will print a * prompt.

Type $L 0: and enter. This will load SALV. Now type $G to start, getting SALV's * prompt.

Type G to check all disks. When done, SALV will go back to RUG through a special entry point which loads and starts SITS.

SITS starts the system sphere which prints SITS IS UP! You can now type ^Z on a teletype or DO IT on a TV keyboard to log in.
