  • TS2068 Port AssignmentsTS 2068 Reference
    Timex provided SYNTAX with the following chart, referred to on page 214 of your 2068 manual. This chart is what you would receive if you contacted Timex Corporation for port assignments.
  • KaleidoscopeZX81 TS 1000 Type-in program
    I resorted to machine code in an effort to write a fast program to display a kaleidoscope pattern on the ZX/TS screen. The resulting images may be viewed on the screen and printed out at will.
  • PiZX81 TS 1000 Type-in program
    This program can calculate PI to over 8000 decimal places— but don’t hold your breath. It takes over 12 hours for 512 digits! The algorithm uses base 100 arithmetic, storing each digit in one byte of a character string (codes 0-99). It is based on the Taylor series for the arctangent.
  • RenumberZX81 TS 1000 Type-in program
    Utility programs for renumbering the lines of BASIC programs facilitate merging with other programs, spreading out line numbers to make room for additional lines, and neatening up finished programs. Changing line numbers is easy, but a useful renumbering utility must also fix the destination line numbers in GOTOs and GOSUBs, a more difficult task. This…
  • Dear EditorZX81 TS 1500 TS 2068 TS 2040 Type-in program
    TS2068 version of Dave Wood’s High Line Numbers; maintaining the ZX81; questions about TS2040, TS2068 and TS1500.
  • BiorhythmsZX81 TS 1000 Type-in program
    I wrote this program as a result of a great disappointment I experienced after purchasing a Biorhythms program from one of the prominent software companies. The program did not print an accurate set of curves, and did not print a mathematically correct result.
  • Not Entirely ClearZX81 TS 1000 Type-in program
    Enter this line by hitting 1, CLEAR, cursor back, REM, NOT, /. Execute via RAND USR 16514.
  • TS2068 Connector PinoutsTS 2068 Reference
    This information, from TIMEX Technical Memo #6, is supplied by TIMEX for publication by SYNTAX.
  • RAND and AutorunZX81 TS 1000 Type-in program
    RAND will not work properly on ZX/TS machines if the program RUNS automatically when LOADed.
  • ROMPAK ROM CardZX81 TS 1000 Hardware review
    ROMPAK permits you to use many programs instantly—cartridges in the rough. An adaptor plugs onto your ZX/TS and provides a socket to contain the program ROM. A simple machine code routine in the ROM moves the program into RAM in under a second, and you’re ready to go.
  • Reusable LoopsZX81 TS 1000 Type-in program
    You can shorten and clarify some of your programs by using one loop and several flag variables to perform related operations. For a sample, let’s take a utility that creates, modifies, moves, checks, and prints a ten-byte MC routine.
  • UM-64 Memory ModuleZX81 TS 1000 Hardware review
    Using bigger memories creates opportunities for greater losses in a crash. Byte-Back’s battery-back-up scheme cuts this risk. You’ll also get the possibility to have your operating system in RAM (all but the characters), compatibility with the TS1500, switch-selectable banks in the 8-16K area, an EPROM socket you can switch-select into 8-16K, and reasonable documentation from…
  • Timex Shows New PeripheralsTS 2050
    Timex displayed new products at the 1984 Consumer Electronics Show in Las Vegas.
  • ZX/TS Users' Groups
  • Vendor Report
    Updates from Synergistic Designs, E. Arthur Brown, G. Russell Electronics; about Timex Sinclair User and KOPAK.
  • Syntax ErrorsTS 2068 Type-in program
    Change Firstloader’s translation table to 32 at 44125 and 14 at 44126. Some Upload tapes from E-Z Key share the error. This doesn’t affect translations, and both programs run correctly. Use a Winky Board II to load ZX/TS tapes. Connector diagrams in this issue supercede information published in SYNTAX Dec. 83.
  • Sinclair Announces QL; Plans US Mkt Re-EntryQL
    Sinclair Research, Ltd announced in London a new machine—the Sinclair QL—using the 68008 processor running at 7.5 MHz. Late February should see initial shipments in the UK, with production building to 20,000/mo by summer. Introductory price in the UK is $599, but the US price will likely be $499 when the machine arrives here, perhaps…
  • Program ImprovementsTS 2068 Type-in program
    To see more ROM calls in Marty Iron’s program translated for the 2068, you must change lines 100 and 210 to use 14446 instead of 7679. Expect run time of about 1 hour. Cassette Labeler needs changes in lines 27 0 and 370 if you want to use full 30-character lines on a 2068 version.…
  • New Products and Services (Syntax v5 n1)ZX81 TS 1000 TS 2068
    New books from Prentice-Hall, Hayden; SRS Speech Recognition System from G. Russell Electronics; DO-CALC; Software from Banta Software; RAMPAGER from Robotec.
