The ROM's source is F18 code in capsules/v4/rom, assembled off the node by v4/tools/mkrom.c with the memory map's constants from v4/tools/mkmap.c (MACHINE.md 2). main.f18 is the entry table payloads call through (2.1); in.f18 reads the console and splits it into tokens exactly as text.c does, the token held packed as a counted string. The ROM's state is a reserved area of the map (host_map.h ROM_*). text.c gains the constant directive, so the off-node assembler and the ROM speak one language. The map also names (NUMBER)'s state, for the next task. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

|
|
* the text assembler's notation, the addresses and codes of

|
* v4/tests/host_map.h that the ROM's source (capsules/v4/rom) uses: the

* console's receive registers and the ROM's state area (MACHINE.md 2.1).
|
|
* The map has one source, host_map.h; this is how the ROM reads it.
