| TS2068 Port Assignments | 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. | Timex/Sinclair 2068 |
| Kaleidoscope | 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. | Sinclair ZX81, Timex/Sinclair 1000 |
| Pi | 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. | Sinclair ZX81, Timex/Sinclair 1000 |
| Renumber | 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 | Sinclair ZX81, Timex/Sinclair 1000 |
| Dear Editor | TS2068 version of Dave Wood’s High Line Numbers; maintaining the ZX81; questions about TS2040, TS2068 and TS1500. | Sinclair ZX81, Timex/Sinclair 1500, Timex/Sinclair 2068 |
| Biorhythms | 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. | Sinclair ZX81, Timex/Sinclair 1000 |
| Not Entirely Clear | Enter this line by hitting 1, CLEAR, cursor back, REM, NOT, /. Execute via RAND USR 16514. | Sinclair ZX81, Timex/Sinclair 1000 |
| TS2068 Connector Pinouts | This information, from TIMEX Technical Memo #6, is supplied by TIMEX for publication by SYNTAX. | Timex/Sinclair 2068 |
| RAND and Autorun | RAND will not work properly on ZX/TS machines if the program RUNS automatically when LOADed. | Sinclair ZX81, Timex/Sinclair 1000 |
| ROMPAK ROM Card | 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. | Sinclair ZX81, Timex/Sinclair 1000 |
| Reusable Loops | 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. | Sinclair ZX81, Timex/Sinclair 1000 |
| UM-64 Memory Module | 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 | Sinclair ZX81, Timex/Sinclair 1000 |
| Timex Shows New Peripherals | Timex displayed new products at the 1984 Consumer Electronics Show in Las Vegas. | |

| Vendor Report | Updates from Synergistic Designs, E. Arthur Brown, G. Russell Electronics; about Timex Sinclair User and KOPAK. | |
| Syntax Errors | 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. | Timex/Sinclair 2068 |
| Sinclair Announces QL; Plans US Mkt Re-Entry | 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 | Sinclair QL |
| Program Improvements | 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. | Timex/Sinclair 2068 |
| New Products and Services (Syntax v5 n1) | New books from Prentice-Hall, Hayden; SRS Speech Recognition System from G. Russell Electronics; DO-CALC; Software from Banta Software; RAMPAGER from Robotec. | Sinclair ZX81, Timex/Sinclair 1000, Timex/Sinclair 2068 |
