Tools · and the record of them

The DOC Toolbox

For twenty years the Derby Owners Club community built its own tools: card editors, breeding calculators, whip-chart spreadsheets, relationship guides. Most players heard of them and never got them. This page is two things at once. First, it is where you download the project's own tools, open, browser-based, free. Second, it is an honest record of every tool the scene made, listed and credited by name so that work is not forgotten, even where it is not ours to hand out.

This page pairs with the English preservation record and the Japanese one, where the people and sites named below are documented in full.

Use it: the project's tools

These are the project's own tools. They run in your browser, they are free, and there is nothing to download and install. Your card files and horse data stay on your machine, in your browser, and are never uploaded. Think of them as the modern, browser-native successors to the old community spreadsheets: the same jobs those workbooks did, rebuilt so anyone can open them on a phone or a laptop without hunting down a decades-old Excel file.

Start here

The tools hub collects every browser tool the project ships in one place. The flagship pages below are the ones most people want first.

Community documents, hosted with the author's permission

The three 2004 DOC Racing Handbooks by Michael Pule ("Michael in Tempe" of the Horse Stable, of doc.rbcb.net), the organised compendium of everything the 2004 community knew. Long heard of, rarely held. The original PDFs, hosted here with Michael's permission.

The record: every tool the scene made

The table below documents the tools the DOC community built over two decades, drawn from the people and sites named on the preservation pages. It is a record and a credit, not a download mirror. Where a tool is the project's own, or a direct evolution of the old spreadsheets, it lives in the section above and you can use it now. Everyone else's work is listed here to honour it and to help you find the makers, several of whom are alive and named on the preservation record. This site hosts no game files and redistributes no one else's software, and there are no download links in this table except to the project's own successor pages.

The one rule this table follows

We list and credit; we do not host other people's tools. A row here means the tool existed and names who made it. Where a maker is alive and reachable, that is noted so the community can ask them directly, on their own terms, about their own work.

Makers are credited for public work only. Where a source used a handle, the handle is what appears here. Nothing on this page includes registration codes, keys, customer names, card data or game files, by design and on principle.
