| Beginning Z80 Machine Code, Lesson 3 | Before we get to our first MC instructions, lets take another look inside our CPU. Inside we will find registers that are called A,F,B,C,D,E,H,L,I,R,IX,IY,SP,PC,A’,F’,B’,C’,D’,E’,H’ and L’. These are not the alphabet soup, that the CPU had for lunch. Registers are merely storage places within the CPU as opposed to external memory (ROM and RAM). | Timex/Sinclair 1000, Timex/Sinclair 2068 |
| Comments by the Editor | A recent comment by Amstrad director, Alan Sugar, sort of “ruffled my feathers” a bit…and I’d be curious to get your reaction as well. To paraphrase, he stated that Sinclair computers were very games orientated, and that his own Amstrad models were for more “serious” applications. | |
| Cosmos: QL Software Review | It is my hope that 2068 owners will read this review as well as those with QLs. A review of ASTRONOMER for the 48K Spectrum appeared in the January/February 86 issue of TIME DESIGNS, and in it I extolled its virtues. | Sinclair QL |
| Datagen | Have you ever typed a long list of information into an array, and then attempted to RUN your program, only to find out that the RUN command wiped out the entire array? The first thing you say to yourself (after cursing at the computer) is “why didn’t I put the data in a Data Statement?” DATA Statements have some other advatages over arrays. | Timex/Sinclair 2068, Type-in program |

| Embellishing MTERM II | As editor of the Portland Area Timex/Sinclair Users Group (P.A.T.S.) newsletter, I wanted to upload the newsletter to members who own a modem, MTERM II, and Tasword. (NOTE: Uploading means sending data from one computer to another. Downloading is receiving data from another computer.) | Timex/Sinclair 2068, Type-in program |
| Games for the Sinclair QL: A Potpourri | Unlike previous Sinclair computers, the Sinclair QL was not–by design–optimized for computer games. The sound and graphics systems of the QL are adapted for professional and business use, partly in an attempt by Sinclair Research to live down a reputation as a producer of computers for children. | Sinclair QL, Type-in program |
| Letters | “I have started a Users Group in the Harrisburg Area. I am having trouble locating users. The name of our Group is: Harrisburg Area Timex Sinclair Users Group. H.A.T.S. meets on the third Wednesday each month. I started the group with a few names I received from Russell Electronics. | Timex/Sinclair 2068 |
| MacIntosh-type Menu for the 2068 | Several months ago, I wrote a weld design program that used two special menus from which a person could select the number of the weld picture that would be most applicable. Figure number one is a print-out of one of these menus (the actual screen display is much more impressionable). | Timex/Sinclair 2068, Type-in program |
| Poly-Scroll | POLY-SCROLL demonstrates a screen utility for a T/S 2068 Demo used at the T/S Computerfest in Ohio. PS uses the alternate display file (Display File 2) to present pictures or data to the observer while it is preparing the next screen on the standard display file (Display File 1). | Timex/Sinclair 2068, Type-in program |

| Software in Review: Colonize the Universe | As Commander of your interplanetary spacecraft, there are certain risks and weighted decisions upon your shoulders. Should you send the probecraft into the ominous Black Hole, only to return without the precious fuel and having spent 10 gallons itself? | Timex/Sinclair 2068 |
| Software in Review: Saboteur! | A recent trend in Spectrum programs brings the action and realism of the Martial Arts to the monitor screen. Such programs as “The Way of the Exploding Fists”, “Yie Ar Kung Fu”, the popular new “Way of the Tiger”, and “Saboteur!”. There are some folks that just don’t appreciate this sort of thing. | Sinclair ZX Spectrum |

| T/S 1000/ZX81 External Keyboard Buffer | If you’re like me, you like to attach not only your memory pack, but also a modem, a printer, a joy-stick interface, an AC controller, and anything else that there is room for behind the computer. | Sinclair ZX81, Timex/Sinclair 1000 |

| TASWORD Word Count Utility Modification | A word count utility is a feature I’ve wanted to add to my copy of Tasword Two for nearly a year. The routine published in the February/March 1986 issue of ZX COMPUTING [a British magazine], is wonderful! Thanks to John Wall‘s article, my already excellent version of Tasword has been made even more useful. | Timex/Sinclair 2068 |
| The Mystery of the Missing 253 | When Timex released its Technical Manual for the TS2068, we learned how to add memory to and switch between its three internal memory banks. This was wonderful stuff, and it’s given us many excellent TS2068 products long after the “profane world” thought that the Timex computer was dead. | Timex/Sinclair 2068 |
| TS 1000/1500 Program Chaining, Part Two | The first part of this series of articles covered: the definitions of Linking and Chaining, how to make a program self running, making one program module load another, and the VARS method of passing data from one program module to another. By data, I mean text, computed variables, arrays or strings. | Timex/Sinclair 1000, Timex/Sinclair 1500 |
| Ultra-Easy Designer Graphics | When I first ordered my 2068 back in, well, what seems eons ago, one thing I looked forward to most was the machine’s touted User Defined Graphics capabilities. What a boon to an old ZX81 programmer this would be! On the face of it, UDGs looked pretty exciting. | Timex/Sinclair 2068, Type-in program |
