Software preservation is the single most active throughline in the group, and the community has converged on a settled toolchain. Capture a clean WAV (a shoebox deck with a TONE control, the Realistic Minisette-9, or the TS2020 itself; Carl Miles is the standing reference here), clean up in Audacity, then run it through tzxtools (tzxwav / tzxplay / tzxmerge) or — when standalone tools choke — load the WAV in FUSE, whose adaptive algorithm rescues files nothing else will. The Fort Worth Timex Users Group's tape-header utility, run alongside FUSE, extracts auto-start lines and code addresses for re-saving. The Yahoo years relied on MakeTZX/PlayTZX/WinTZX 2.33, Warajevo, and the Lunter Z80 emulator's tape2tap. Two hard cases got their own tools: Martin Vindahl's frequency-based zx81-dat-tape-reader (looks for 3.2 kHz instead of amplitude) cracks ZX81 WAVs the rest can't, and Leandro Radel's tape2wav reverses opaque TZX blobs back to WAVs that tzxwav can then re-encode. A cross-cutting hardware lesson Ariel Ranieri keeps repeating: the TS2068's EAR jack is half-deaf, so loading from a phone or PC almost always needs a powered speaker in-line.
The preservation effort has a clean two-era arc. In the Yahoo years (2001–2019) Bruno (zxbruno) and Andrew Owen did the heavy lifting: Bruno chased authors and publishers for explicit permission and uploaded relentlessly; Andrew Owen consolidated everything into the World of Spectrum Timex archive, then dumped the full set into the group's files area in 2010 when WoS stalled — including new Interface II→Timex cart conversions. He even recreated never-released or lost carts (Swordfight, Penetrator, Budgeter, VU-File, VU-Calc) by snapshotting loaded state into DCK images. The single most consequential Yahoo-era thread was 2015–17's Copyright Status discussion, where Bruno got Timex (via Mr. Lou) to declare in writing that any documentation marked 'copyright Timex/Timex Computer Company' is public domain, and to confirm no Timex source code or warehouse stash survived the early-2000s facilities move.
The groups.io era (2020→) is broader and more hardware-complete. David Anderson scans books and newsletters straight to archive.org (TS Color Graphics, The Timex Sinclair 2068 Explored, OHTSUG newsletters, Creative Games for the TS2068, his own 2023 TS2068 ROM Disassembly book) and works through bulk lots — CATS user-group library tapes 8 and 9, Bob Swoger's QED, Sprites 2068, Tech-Draw, PC-Draw, Zebra material, Quicksilver Spectrum-to-2068 conversions. Adam Trionfo opened an author-direct recovery track: after writing to Dan Tandberg he drove to Dan's garage sale and walked out with five Calliope Software tapes (Mazeball, Metagraphics, Starblasters, two Timeblasters versions), then archived, disassembled and documented them. Rampager is the one Calliope title still hunted. Adam's flagship Library Tape Archiving project, started 2022 from Ryan Gray's loaned tapes, is still going in 2026 — Michael Hart staged the FW-TSUG-II WAVs on Drive in May. The era's emotional centerpiece is Jack Boatwright, a Yahoo-era surplus-hardware lifeline since 2002, who lost most of his saved collection in a 2024 garage fire and shipped the survivors (tapes, disks, Hot-Z ROMs, an extensive John Oliger collection, a -02 prototype 2068 board) to David in six boxes.
The community has also begun building second-order projects on top of the archive: David's WordPress catalog plugin that uses Claude to auto-describe ~1,000 archived 2068 programs from their BASIC source (rendered in a deliberately retro shareware-catalog style); Tim Swenson's ports of Cauldwell's Spectrum games to the 2068 once source archives were in reach; and a longer conversation about whether an actual American Timex museum is feasible (Tim's hard-won perspective from running two local history museums: founder-control and stewardship matter more than the collection). Several threads in this topic drifted in from elsewhere — the long Modems-and-VoIP thread becomes an archiving thread once the discussion turns to making TZX files from captured BBS audio, and the Speech Synthesizer demo thread is here because Adam recorded the demo as a preservation artifact.
Key threads
- Copyright Status of 2068 ROMs (archive.org) — Yahoo-era 2015–17 thread where Bruno gets Timex to declare all copyright-Timex documentation public domain and confirm no source/warehouse survived the early-2000s move — the legal foundation everything since rests on.
- Timex Archive uploaded (archive.org) — Andrew Owen's 2010 dump of the entire WoS Timex archive (plus his new Interface II→Timex cart conversions) into the group's files area after the WoS project stalled — the Yahoo era's consolidation moment.
- missing carts recreated (archive.org) — Andrew Owen's 2011 reconstructions of carts that were never released or are lost (Swordfight, Penetrator, Budgeter, VU-File, VU-Calc) via DCK snapshots — preservation by recreation, not just digitization.
- T/S 2068 Library Tape Archiving Process (#2347 on groups.io) — Adam's flagship groups.io-era project, started 2022 from Ryan's loaned library tape and still active in 2026 (FW-TSUG-II WAVs now staged on Drive by Michael Hart) — best single thread for the modern workflow.
- Archiving 'Timeblasters' by Calliope Software (#3129 on groups.io) — Exemplar of the author-direct recovery model: Adam writes to Dan Tandberg, walks out of his garage sale with five Calliope tapes, then archives + disassembles them — work impossible in the Yahoo years when Dan was uncontacted.
- A plethora of programs (#3424 on groups.io) — David's 2023 bulk-archiving weekend pulling Tech-Draw, Sprites 2068, Bob Swoger's QED and Zebra material off purchased tapes — also where Ryan introduces tape2wav as the rescue path when tzxtools can't decode a WAV.
- Help me fix a file in The Crown? (#5436 on groups.io) — Multi-day deep dive on why FUSE will load a WAV that standalone tools choke on (its adaptive algorithm), with Ryan documenting the Audacity-then-FUSE-then-tape-header-utility rescue workflow that's become standard.
- zx81 tape recovery (#2784 on groups.io) — Larry's discovery of Martin Vindahl's zx81-dat-tape-reader (frequency-based, 3.2 kHz detection instead of amplitude) — the tool that unlocks the otherwise unrecoverable ZX81 WAV case.
- From Eric Johnson, by way of Jack Boatwright (#6541 on groups.io) — Jack — a Yahoo-era surplus-hardware lifeline since 2002 — loses most of his saved collection to a 2024 garage fire and ships the survivors (tapes, Oliger hardware, a -02 prototype 2068 board) to David. Clearest cross-era continuity thread.
- A work in progress software catalog (#9137 on groups.io) — 2026 second-order use of the archive: David's WordPress plugin auto-describes ~1,000 archived 2068 programs from their BASIC source and renders them as a retro shareware catalog — what preservation enables once it's done.
