saturnus 0.11.0 brings an HP 100LX or 200LX palmtop into Files, lets Files
use the 49G's XSERV, makes Files simpler, and offers the calculators to
your browser's own AI (WebMCP).

Get it
- On the web, nothing to install: https://ractive.ch/saturnus/app/
(Chrome, Edge or Firefox for a serial cable; every browser for the
emulated calculator).
- The desktop app saturnus_0.11.0_… (on Linux saturnus-app), with
a -SHA256SUMS file beside them:
- macOS, Apple silicon: .dmg, signed and notarised, or brew trust --cask ractive/tap/saturnus-app once, then brew install --cask ractive/tap/saturnus-app;
- Windows: .msi or -setup.exe for x86_64 (x64) and ARM (arm64);
- Linux: .deb, .rpm or .AppImage for x86_64 (amd64, x86_64)
and ARM (arm64, aarch64). Add yourself to the dialout group to
use a serial port.
- The command-line tools saturnus and satx: cargo install,
Homebrew ractive/tap, Scoop ractive, or the archives and Linux
packages below.
- Libraries on crates.io, all at 0.11.0, among them the new
filer-proto.

Files
- An HP 100LX or 200LX palmtop. "Add a calculator…" offers "An HP
100LX or 200LX palmtop": put its Filer in server mode, and Files shows
its drives, folders and files, copies both ways (whole folders too),
renames, deletes and makes folders. 19200 baud by default. Use the
palmtop's own cable, never on a 48 or 49G.
- XSERV on the 49G. Type XSERV on the 49G instead of SERVER, and
Files finds it by itself: about twice as fast as the Kermit server,
and the list does not depend on the display. For PICT, backup and
restore Files starts the Kermit server inside XSERV and comes back.
- One connect step. Files reads the model from the calculator: the
connect step shows each model's keys, and the model picker and the
Settings dialog are gone ("Use a fixed speed" is under "Trouble with
the cable?").
- A calculator that stops answering says so, after 25 seconds on the
Kermit server or 8 on XSERV, with the keys to start it again and
Reconnect.
- Fast transfer by one key on the 48GX (and a 49G without XSERV):
Files puts the command on the calculator's stack, and you press EVAL.
- A 38G, 39G or 40G sees new files at once, without serving again.

Your AI
- The browser's own AI (WebMCP). In a browser with WebMCP (Chrome 149
and Edge 150 try it out on saturnus's site), the calculators' tools are
offered to the browser's AI as well, with no address or code. The app
adds no question of its own; the browser or its AI decides whether to
ask you before storing or purging a variable (Brave's Leo asks before
every call). Connecting an AI app through the dialog works as before.
- A cancelled AI call stops at once and leaves no keys behind.

satx
- satx lx: files on an HP 100LX or 200LX over its Filer.
- XSERV: satx info says which server answered; satx xserv was
tested on a real 49G.
- A real 49G read whole. The 49G sends each stack level only as wide
as its display, so satx info failed on a 49G with ROM 1.18; IOPAR and
the version are now read in pieces, in any display mode.

Smaller changes
- The home page says "Add an emulated calculator" and "Connect a real
calculator".
- The reference gives the 49G's EVAL key (right-shift, SYMB); the
Reference tab names search's key.
- Pressed buttons keep their look under the pointer.
- Disconnect lets go of the serial port within 30 seconds.

saturnus 0.10.3 fixes what two code reviews found: quitting the desktop app
now saves, and failed writes, backups and directory changes clean up after
themselves.

Get it
- On the web, nothing to install: https://ractive.ch/saturnus/app/
(Chrome or Edge for a serial cable; every browser for the emulated
calculator).
- The desktop app saturnus_0.10.3_… (on Linux saturnus-app), with
a -SHA256SUMS file beside them:
- macOS, Apple silicon: .dmg, signed and notarised, or brew trust --cask ractive/tap/saturnus-app once, then brew install --cask ractive/tap/saturnus-app;
- Windows: .msi or -setup.exe for x86_64 (x64) and ARM (arm64);
- Linux: .deb, .rpm or .AppImage for x86_64 (amd64, x86_64)
and ARM (arm64, aarch64). Add yourself to the dialout group to
use a serial port.
- The command-line tools saturnus and satx: cargo install,
Homebrew ractive/tap, Scoop ractive, or the archives and Linux
packages below.
- Libraries on crates.io, all at 0.10.3.

Desktop app and web page
- Quitting the desktop app saves the calculator. Cmd+Q on a Mac now
saves an unsaved change, as closing the window always did.
- A fresh start keeps what it should. A ROM that doesn't boot no longer
deletes the kept state. A ROM that boots as another model reads or clears
that model's state, not the one you asked for.
- A failed save leaves the old file. The desktop app writes saved files
and its AI access setting to the side, then moves them into place.

satx and Files
- A variable name with @ is refused. The calculator reads @ as the
start of a comment, so satx and Files no longer take such a name.
- A directory that isn't there changes nothing. satx --dir, satx ls PATH and the REPL's :cd and :ls leave the calculator where it was
when a name in the path is missing, not part of the way down it.
satx xserv goes back to HOME, as XSERV can't say where it was.
- A backup that fails no longer leaves its copies behind. satx backup
and Files remove the copy in port 0 when the calculator runs out of
memory, and a backup of an emulated calculator whose server stops
answering removes what it made. A port copy it can't be sure of stays,
and the error says so.
- Files replaces a variable with a long name. The swap goes out as three
commands when it doesn't fit in one packet. A name too long even for that
is refused, and the old variable stays.
- satx get --force replaces a file whole. A failed write leaves the
old file, and a new file it could not finish is removed. In a directory
where satx can't create a file, --force still writes in place, so a
failed write there loses the old content.
- Smaller fixes. satx rm X X deletes X once instead of failing on the
second. satx repl --json sends nothing more once its reader has closed.

Emulator
- A transfer that fails lets go of a key it held down.
- A UART break that is looped back and let go early leaves the receiver
idle (inferred: the manual covers a full break only).
