TS1000 / ZX81 / TS1500

TS1000, ZX81, and TS1500 — the 1K/16K Sinclair machines and Timex equivalents.

263 threads · 1552 messages · 2002-10-27 → 2026-10-16

TS1000, ZX81 and TS1500 threads are mostly about getting old machines running again. When Carlos Nunez's TS1000 went from static to a solid black screen with no K cursor, Patrick Leclerc suggested an RCA-to-F-type coax adapter instead of the original TV/Computer switch box and pointed to the VLA81 ULA replacement from vRetroDesign. Claudius warned that taking a ZX81 past 48K is impractical and that the Memotech 64K Mempack could damage the machine. Kevin Dorff, Tim H and others covered keyboard repair: replacement ZX81 membranes from RWAP Software and ZX Renew, a tactile drop-in keyboard, and a five-line BASIC memory test for internal 16K upgrades. John Mobley's ZX80 turned out to be a NTSC UHF unit that only needed the TV tuned near channel 35. Chapas's "broken" TS1500 was fine. The test files were Spectrum audio, and David Anderson pointed out that a 2000-series tape will almost never load on a 1000-series machine.

Carl Miles did most of the hardware work. His TS1000-to-TS1500 conversion fits a 16K RAM upgrade, a composite mod, a switching regulator in place of the 7805, an original TS1500 ROM (so TS1510 cartridges auto-run) and a silver-and-gray paint job. He documented Argentine Czerweny machines: the CZ2000, built on an Issue 6A Spectrum board with a PAL-Nc crystal, and a cost-reduced CZ1500 with two 16Kx4 RAM chips. He built a Wilco2009 ZX80 clone alongside Paul Farrow's Chroma80, and measured capacitors in Mowgli's TS1500s. Ryan Gray and Joao Diogo Ramos sorted out where the machines were made: Sinclair units in Dundee, Scotland, and Timex Sinclair units in Portugal. Jimmy Ipock identified a Timex EPROM store demonstrator for the TS1000 and recorded it running a bar graph and a recipe scaler on real hardware.

On software, Adam Trionfo's Calliope Software work started with Dan Tandberg's Starblasters, typed in from SYNC on a real TS1000 and saved through EightyOne. Metagraphics followed: the ZX81 Tape Converter threw errors, and Ryan later traced the TZX to Martin Vindahl's zx81-dat-tape-reader, which Larry Lorenson had introduced and Joe VandeZande got running. John Stroebel described EightyOne's Wav Loader and Tape Manager for saving to and feeding real machines. The Yahoo-era threads are the 2007 question of which Sinclairs reached the US (a ZX81 before the TS1000, with the TS1000 board switchable between PAL and NTSC) and the 2009 Zebra thread, where Al Hartman offered TS1000 tape bundles. Several threads only drifted into this topic: the TS Pico tape thread (which became a Hi-Z breakpoint discussion for TS1000 code), Paul DeMelto's "Hello!" introduction, the Z80 cross-assembler thread, the 2068 recapping thread, "The Timex 1000 isn't a 2068", and Michael Hart's reel-to-reel project.
