00 — Installation Concepts & Terminology

Status: SCAFFOLD. Verified facts cited from the SINTRAN-H archive (Admin/install-log.txt).

MACM (the bootstrap loader)

MACM is the standalone loader that runs before SINTRAN to load the OS from floppy onto the disk and to cold-start the system. The banner identifies the build, e.g. M A C M - 1 7 1 8 - K (verified, H install-log).

Verified MACM commands (from H install-log banner):

Command	Meaning
)REDEF	Redefine disc type
)HENT	Get SINTRAN from the save-area
22!	Start SINTRAN
10,0$	Load SINTRAN from diskette

Save-area / )HENT vs )GJEM

• )GJEM (save) and )9BYTT are executed at the end of the floppy load (verified, H log).
• Later cold starts: load MACM from SINTRAN DISKETTE-I, type )HENT, wait for line feed (verified, H log).

The install phases

1. Bootstrap (MACM, floppy → disk) — 02-BOOTSTRAP-MACM.md
2. File-system init — 03-FILESYSTEM-INIT.md
3. S3 configuration — 04-S3-CONFIGURATION.md
4. Patches — 05-PATCHES.md
5. Startup & terminal config — 06-STARTUP-AND-TERMINAL-CONFIG.md

TODO

• CPU type / ID and how MACM build maps to CPU — source not located.
• Exact meaning of )9SBLO, )9BYTT octal/loader directives.
