The instructions only ever covered the weather. They are now four pages: what you decide, how signs and spoilage work, what the sky does, and what the street does - the fair and the rival included, with each condition named and what it does to your day spelled out. Every passage that was reproduced from the original has been rewritten: the welcome, the ledger heading, the thunderstorm, the road works, the heat wave, the bankruptcy line and the cost announcements. A project released under copyleft has no business licensing words it did not write, and now it does not have to. NOTICE.md records what changed and why, and narrows the borrowed material to the town's name and the ledger's labels - neither of which is a copyright question. Shortening the ledger heading also fixes the pill that was wrapping to two lines in the remaster. Checked in both skins: all four pages fit the tube at full size, with room to spare.

## What this is
|
|
|
|
An independent reimplementation of the lemonade-stand business simulation that
|
|
went round schools and home computers from the 1970s onward, written from
|
|
scratch in TypeScript in 2026.
|
|
|
|
## Credit where it is due
|
|
|
|
- **Bob Jamison**, Minnesota Educational Computing Consortium (MECC), 1973 —
|
|
wrote the original *Lemonade Stand* for time-shared systems.
|
|
- **Charlie Kellner**, 1979 — wrote the Apple II version that most people
|
|
actually remember, distributed by Apple Computer.
|
|
- Every magazine and type-in book that carried a listing of it, which is how a
|
|
lot of us first met the thing.
|
|
|
|
This project is not affiliated with, endorsed by, or connected to MECC, its
|
|
successors, or Apple. No original source code was used, consulted or copied.
|
|
|
|
## How this code came to exist
|
|
|
|
Clean-room, and worth being specific about because it is what makes the licence
|
|
below meaningful:
|
|
|
|
- **The simulation is ours.** The demand curve, the weather profiles, the sign
|
|
returns and the event probabilities in `src/game/constants.ts` are a
|
|
reconstruction, tuned by running several hundred headless seasons until the
|
|
game *behaved* the way it is remembered. It is not the original arithmetic,
|
|
and it is documented as a reconstruction in the source.
|
|
- **The rules are not ours to own.** Buy glasses, buy signs, set a price, read
|
|
the weather — game mechanics are ideas rather than expression, and nobody
|
|
gets to fence them off. We use them freely and so may you.
|
|
- **The artwork and the music are ours.** Every pixel is SVG drawn in code and
|
|
every note is generated by the synth in `src/audio/`. There are no imported
|
|
assets of any kind.
|
|
|
|
## What is and is not ours
|
|
|
|
**All of it is ours, with two narrow exceptions noted below.**
|
|
|
|
Earlier drafts of this project reproduced some of the original's on-screen
|
|
wording from memory — the welcome, the report heading, the thunderstorm and
|
|
road-works messages. That text was someone else's writing, and a project
|
|
released under a copyleft licence has no business licensing words it did not
|
|
write. Every one of those passages has since been rewritten in our own voice.
|
|
Nothing quoted remains.
|
|
|
|
Two things are still not original, and neither is a copyright question:
|
|
|
|
- **The setting.** The town is still Lemonsville, California. Names and short
|
|
titles are not subject to copyright, and it is kept deliberately, as the one
|
|
visible nod to where the game came from.
|
|
- **The ledger's labels.** `GLASSES SOLD`, `COST OF SIGNS`, `PROFIT` and the
|
|
rest are the only sensible words for what they label, and the order they
|
|
appear in follows from the arithmetic. There is no creative expression in
|
|
them to own.
|
|
|
|
Everything else — the simulation, the artwork, the music, the interface and
|
|
every word on screen — was written for this project and is covered by the
|
|
licence below.
