| 1000 + 1 Nights | One of the more user UNfriendly attributes of the TS 1000 is the slowness with which a new, full screen is built up on the CRT. Non-programmer users express dismay; since the information is all present “inside” the computer, why does it take so long to display it? | Timex/Sinclair 1000 |

| 64 Column Mode Software for the Timex Sinclair 2068 | How would you like to be able to place on the screen 24 rows of 64 characters in your own programs? Or how about plotting in an ultra-high resolution mode of 192 vertical pixels by 512 horizontal pixels? Sound enticing? Then read on… Basically speaking, I have developed several small machine code routines which handle | Timex/Sinclair 2068 |
| A Serial Interface Project for the ZX81 & TS1000 | This is the second article of a series dealing with a serial interface with which to connect your ZX81/TS1000 to a printer, modem or other device. Part one dealt with the actual wiring of the circuit; this one will cover the programming required to obtain useful work from the device. (For those who missed Part | Timex/Sinclair 1000 |

| Beta Basic More About Display Windows | Before we move on to other comparisons between T/S Basic and the extended QL and Beta Basics, a few notes on TS/Spectrum displays might be of interest. As you know, two screen displays or windows are normally available: the main display of 22 lines and the input status display of two or more lines at | Sinclair QL, Timex/Sinclair 2068 |

| Food for your TS-2068: A Private-Key Cryptosystem | The subject this month will be cryptography. Cryptography, as you all know, is the science of disguising information into unintelligible code that would be worthless to any would-be trespasser. The 2068 computer, because of its speed and ability to manipulate large character arrays, makes an excellent secret-coding machine. The program I will present below is | Timex/Sinclair 2068 |

| Hidden Keyboard Commands on Your TS-2068 | You’ve just handed over your hard earned cash fora new TS-2068 computer and hurry home to set up the system. After working your way through the excellent manual provided, you discover that at times when entering your listing some unexplained actions take place on your monitor as the listing is displayed. You also notice that | Timex/Sinclair 2068 |

| Kitchen Table Math Series and Problem Solving | I received several responses to my plea for “help” in locating а workable TS-1000 in a recent copy of this magazine. Thank you, to the several who responded and a very special “thank you” to Bob Hartung of Palmyra, New York, now in indiana for putting me in touch with 47th Street Photo in New | Timex/Sinclair 1000, Timex/Sinclair 2068 |

| QL on I.C.E. | When many people think about the current class of home computers, one of the things that comes to mind is icon control. The first home computer which made this popular was the Apple MacIntosh. When you ask for a directory of files on a disk, the files appear on the screen represented by small pictures | Sinclair QL |

| Scroller | This program, like my previous one is a basic “Scroll left” routine. However, with my last one, I could only enter a 64 character message into memory. This program not only allows you to enter any message up to 15K characters in length but will also let you use various “flash words” in you message | Timex/Sinclair 1000 |
| Simple T/S 2068 Out Port | As stated in part 1, the outputs of the Port or latch can drive LEDs directly however, it would be preferred to isolate the output circuitry using optoisolators. | Timex/Sinclair 2068 |
| Snapshot of TS-2068 System Variables | Investigating the dynamic areas of memory in the TS2068 is liking nailing jelly to the wall. Certain system variables point to the location of these areas, but you can’t find out their values. As soon as you PEEK into these system variables, you change them. The program presented here allows you to look at some | Timex/Sinclair 2068 |
| T/S 2068 Software Review "Spectax85" | Just a short time back when I was turnin my mind to thoughts of (UGH!) 1040s and the associated alphabetical list of “Schedules,” I got aholt of a program designed to help a guy do his/her annual “voluntary” (HA!) submission of revenue to the revenoors. It was submitted to me for review and comment, although | Timex/Sinclair 2068 |
| The Expandable ZX-80 and ZX-81 | Hardware Projects for the Sinclair ZX Mini Computer for the Hobbiest by a Hobbiest In the modern computer are a number of small electronic packages by which contain hundreds and even thousands of semiconductor devices all designed to either turn something on or something off. These are called Integrated Circuits. Some, however, are designed to | Timex/Sinclair 1000 |

| Timex Computer Corporation Speaks! An Interview with Dan Ross | On September 29, 1983, just weeks before the general availability of the Timex Sinclair 2068 Personal Color Computer, I had a personal interview with Dan Ross, VP of Operations of Timex, and the man responsible for the overall operation of the Timex Computer Corporation. Mr. Ross was on a whirlwind tour around the United States | Timex/Sinclair 1000, Timex/Sinclair 2068 |
| Using the John Oliger Expansion System to Create Instant-Load (EPROM) Software for TS/1000 Computers, Part III | In part Il last month, we showed you how to program two 2764 eproms, one with HOT-Z, the other with the Oliger machine code downloading routine. Now, we are ready to program our final eprom with “CETCH2”. This is my program which demonstrates some of the features of the Oliger Video Upgrade. | Timex/Sinclair 1000 |
| Using the Timex 2040 Printer | If you have been using your Timex 2040 printer for only program listings and screen copies, you haven’t been tapping its full potential.
