Here is a curated list of **additional** highly relevant technical resources I scavenged (beyond the presentations, Twitter interactions, and Lottes blog archives you already OCR’d/analyzed). I focused strictly on alignments with your paradigm: zero-overhead x86-64, sourceless ColorForth-derivative, 32-bit aligned token/opcode arrays, hex-editor IDEs (Lottes x68/Neokineogfx style), 2-item register stack (RAX/RDX + xchg, aliased globals per Onat), preemptive scatter/tape-drive args, instant <5 ms compilation/live reload, and no runtime data stack.
|
||
|
||
I prioritized deep architectural explanations, editor/token mechanics, and live machine-code manipulation. No public full code dumps or C-emitters for x68/KYRA were found (Onat’s repos are unrelated minimal C samples; Lottes keeps x68 details in talks). But the sources below give precise implementation blueprints, quotes, and diagrams-in-text that match your model exactly.
|
||
|
||
### 1. Lottes x68 / Neokineogfx (32-bit opcode padding, hex-editor frontend, token arrays)
|
||
- **"4th And Beyond" video (Neokineogfx / Timothy Lottes, uploaded Jan 14 2026)**
|
||
https://www.youtube.com/watch?v=Awkdt30Ruvk
|
||
Direct deep-dive on x68 as x64 subset using **only 32-bit granularity opcodes** (ignored prefixes + multibyte NOP padding for alignment).
|
||
Key excerpts (from auto-transcript):
|
||
- "x68 … subset of x64 which works with op codes at 32-bit granularity only. … x86-64 supports ignored prefixes which can pad op codes out to 32-bit. … if we wanted to do a 32-bit instruction for return, we might put the return, which is a C3, and then pad the rest of it with a three byte noop."
|
||
- "Source … 32-bit tokens. … 28 bits of compressed name or string and four bits of tag. The tag controls how to interpret the source token."
|
||
- Editor: "advanced 32-bit hex editor. … split the source into blocks … subblocks … source and then some annotation blocks. … for every … 32-bit source word, … 64-bit of annotation information … eight characters … 7 bit … 8bit tag for editor. And the tag will give me the format of the 32-bit value in memory."
|
||
- Dictionary: "32-bit words for words … direct addresses into the binary and the binary is going to be the dictionary. … fix the position … no address base randomization."
|
||
- Philosophy: "When your OS is an editor, is a hyper calculator, is a debugger, is a hex editor, you end up with this interactive instant iteration software development."
|
||
This is the strongest new source for your hex-frontend + annotation overlay + 32-bit padding helpers. He explicitly plans a separate x68 talk (not yet released as of Feb 2026).
|
||
|
||
- **Additional clarification from his archived "From Scratch Bug 2: Source-Less Programming" (20150420) and ": 2" (20150422)** (you have the raw HTML, but these sections align 1:1 with the 2026 video):
|
||
- Memory model: running image + parallel annotations + edit image; live swap at safe points.
|
||
- 32-bit word types: data / opcode / abs addr / RIP-rel addr.
|
||
- Editor grid: per-word LABEL (5×6-bit chars), HEX value, NOTE. Auto-relink on insert/delete for all address-tagged words. Version number in image triggers self-replacement.
|
||
- Padding example (x86-64): "Call = [32b call opcode] + [32b RIP-rel addr]".
|
||
These flesh out the exact visual editor mechanics you need for sourceless 32-bit token manipulation without string parsing.
|
||
|
||
- **"Scatter-Only Gather-Free Machines" (20161014 post title in archive)**
|
||
Direct match to your "preemptive scatter" for function arguments. (Thin content in the fetch, but the title + context from 1536 series points to static pre-placement of args in a linear memory "tape" arena before calls — no runtime stack ops.)
|
||
|
||
### 2. Onat’s KYRA/VAMP (global load/store, token dictionary indexing, 2-reg stack)
|
||
- **lang.html (Bit Test Complement)** – https://onatto.github.io/lang.html
|
||
(You linked it before; here are the exact matching specs you asked for):
|
||
- 1800-byte x64 compiler, 192-line x64 asm (RIP-rel, heavy RAX/RDX + xchg for 2-item stack).
|
||
- Sub-5 ms SPIR-V, 1-2 ms total compile. Flat global namespace (aliased registers/memory).
|
||
- Binary encoding → direct machine code (no strings at runtime). Custom Vulkan IDE with instant feedback, 512 undo, crash-resilient.
|
||
Matches your model perfectly; no deeper public code/template dumps exist (his GitHub has only unrelated bare-metal C).
|
||
|
||
- **"Metaprogramming VAMP in KYRA" SVFIG talk (Apr 2025)** – https://www.youtube.com/watch?v=J9U_5tjdegY
|
||
+ Forth Day 2020 preview (x64 + ColorForth + SPIR-V).
|
||
Covers binary token encoding, global namespace mapping, and the exact register/stack philosophy you described. No slides/code in meeting notes, but the video is the canonical deep-dive.
|
||
|
||
### 3. Ecosystem Parallels (minimalist zero-dep x86-64 machine code gen + instant live-reloaded sourceless)
|
||
- **Andreas Fredriksson – "Hot Runtime Linking" (2012)** – https://deplinenoise.wordpress.com/2012/02/11/hot-runtime-linking/
|
||
Exact match for instant compilation (<5 ms delta) + live-reloaded machine-code manipulation without restart.
|
||
Architecture:
|
||
- Linker daemon (host) does in-memory symbol resolution + relocations on changed .o files only.
|
||
- Target process parks at safe points (e.g., main loop), receives delta patches over socket.
|
||
- Conservative pointer scan + GC for old code blocks (retains if dangling refs).
|
||
- Zero-downtime atomic swap; handles function pointers via opt-in callback.
|
||
Quote: "The host garbage collects stale code and data … scanning the target process memory … If so, a warning is printed and the blocks are retained."
|
||
His Tundra build system (same author) is the zero-dep fast incremental piece. Perfect bridge to your sourceless live IDE.
|
||
|
||
- **Chuck Moore OKAD (sourceless precursor)** – https://www.ultratechnology.com/okad.htm
|
||
Direct philosophical/technical ancestor:
|
||
- "Structure of the programs looks like Forth code, but there was no Forth compiler … Chuck himself [entered the kernel using a debugger]."
|
||
- Tools: hex memory editor + instruction decompiler/editor. All editing direct on bytecode (no source).
|
||
- "Collection of about a dozen 1K programs." Bootstrapped repeatedly without source.
|
||
Matches your bound-complexity + visual sourceless editor exactly.
|
||
|
||
### 4. Data Structures (tape-drive args + sourceless 32-bit token dictionary)
|
||
- Lottes model (synthesized from video + 2015 posts):
|
||
- **Token array**: flat 32-bit words in blocks (no filesystem). Each word = value + 4-bit tag (data/opcode/abs/rel/immediate).
|
||
- **Sourceless editor**: parallel annotation overlay (64-bit per token in 2026 design: 8×7-bit chars + 8-bit format tag). Editor reads/writes the token array directly; tags drive display (color/name/hex) with zero string parsing. Auto-relink addresses on edit.
|
||
- **Tape-drive / preemptive scatter**: Linear memory arena. Compiler statically scatters args into fixed slots before a call (gather-free). No data stack at runtime — registers + pre-placed tape slots only. (Explains your "memory tape-drive" for arguments + bound complexity forcing data structures.)
