Books and manuals are one of the longest-running concerns of the community, and the through-line is preservation: identifying what existed, finding physical copies, scanning them, and then annotating and re-publishing them. In the Yahoo-era (2001–2019), the work was ad-hoc — members like Bryan Vines (2004) volunteered office copiers to PDF the SAMS Beginner/Intermediate Guide, Intermediate/Advanced Guide, and the official T/S 2068 User Manual, while Jack Boatwright surfaced still-shrink-wrapped stock of T/S 2068 BASICs and Beyond by Sharon Zardetto Aker. Even into 2015, threads were still about chasing rare manuals (the Zebra OS-64 cartridge manual surfaced via member scans after the cartridge itself was being fought over on eBay).
The groups.io era (2020→present) turned that ad-hoc effort into a pipeline. David Anderson's timexsinclair.com bibliography plus archive.org uploads became the backbone, and a steady cadence of "is anyone holding an unarchived book?" threads pulled in scans of Creative Games for the Timex Sinclair 2068 (Maunder, 1984), Multi-Draw 2068 manual, Timex Sinclair Color Graphics, The Timex Sinclair 2068 Explored (Hartnell), the Ottawa-Hull TSUG newsletters, and the Beepers: 21 Electronics Projects book. Adam Trionfo's pattern of typing in cassette companions on real hardware — Jeff Mazur's PSG sound examples from the Intermediate/Advanced Guide, then Richard Booth's Applied Sinclair: Subroutines for the Mathematically-Minded — closed the loop between scanned book and runnable code, with Booth himself joining a Zoom meeting as guest speaker.
The community has also moved beyond just scanning into producing new reference works that synthesize prior-era material. David's annotated TS 2068 ROM Disassembly book (begun 2022) explicitly pulls from the Yahoo-era ROM disassemblies that circulated on the old list, plus Bob Orrfelt's and Lloyd Dreger's work, Wes Brzozowski's bank-switching series, and the third-party programmer's guide Jeff Mazur provided — Jeff Burrell then completed the keyboard table and EXROM section. Tim Swenson's Z88 Sourcebook and The Sinclair QL in North America are similar born-in-the-community references. For learners, Spectrum-era books (Introduction to 2068 Machine Code, ZX Spectrum Assembly: Let's make a game?, The ZX Spectrum on Your PC) keep getting recommended as the bridge into the hardware.
Most recently (2026), the group has become a critical reader of newly published outside books — Shaun McClure's A Guide to TS 1000/1500 Games drew measured praise mixed with sharp critique that the author had simply search-replaced "ZX81" with "TS 1500" for the US edition despite the 1000 being the prevalent American model. That kind of close-reading is itself a legacy of the deep familiarity built over two decades of scanning, typing in, and annotating these texts.
Key threads
- TS 2068 Books (archive.org) — 2004 Yahoo-era thread where Bryan Vines volunteered to scan the SAMS Beginner/Intermediate Guide, Intermediate/Advanced Guide, and official User Manual to PDF — the earliest organized digitization push for the foundational T/S 2068 documentation.
- Zebra OS-64 Cartridge on Ebay / OS-64 Manual (archive.org) — 2015 Yahoo-era thread that pivots from an eBay bidding war into recovering the rare OS-64 cartridge manual via a member scan — typical of the pre-pipeline era when documentation rescue happened opportunistically alongside hardware hunts.
- New books and newsletter uploaded to archive.org (#87 on groups.io) — 2021 thread that effectively opens the groups.io-era book pipeline: David announces archive.org uploads of Timex Sinclair Color Graphics, The Timex Sinclair 2068 Explored, and Ottawa-Hull TSUG newsletters, and Adam follows up cataloging his 25-book personal collection against the timexsinclair.com bibliography to find unarchived gaps.
- TS 2068 ROM Disassembly book (#1422 on groups.io) — 2022 thread where David shows the work-in-progress annotated ROM disassembly that explicitly fuses Yahoo-era source material (Orrfelt, Dreger, the old list's disassemblies, Wes Brzozowski's bank-switching articles) with new annotations — the clearest example of the community producing new reference works on top of old-era output, with Jeff Burrell jumping in to complete tables and the EXROM.
- Does Anyone Own "Creative Games for the Timex Sinclair 2068?" (#1441 on groups.io) — 2022 thread that captures the modern workflow at its best: Adam identifies an unarchived 1984 book, Louis Florit happens to own it, scans it within a day, and David uploads it to archive.org — the entire scan-and-publish cycle in one short thread.
- Math Subroutines Book by Richard Booth (#3782 on groups.io) — 2023 thread where the book's original author joined a Zoom meeting as guest speaker, and Jeff Burrell converted the long-lost cassette companion programs from text via zmakebas while Adam typed examples in on real 2068 hardware and ran the plots — preservation completed into runnable code, with the author present.
- Beepers: 21 Electronics Projects for the Timex/Sinclair 1000 and 1500 (#3630 on groups.io) — 2023 thread tracking a still-unarchived electronics-projects book through the community: a hardcopy is mailed to David, a similar archived sibling book is located, and members compare notes on circuits they built (or didn't) — illustrates how the books topic blends into hardware-projects stewardship.
- A new book (#9217 on groups.io) — 2026 thread reviewing Shaun McClure's newly published A Guide to TS 1000/1500 Games — community is no longer just preserving old books but critically engaging with new ones, including catching that the US edition appears to be a careless search-replace of ZX81→TS 1500. Shows how two decades of close reading have produced a sharp critical audience.
