One-off newsletter, published by Tim Swenson, that is an ode to the ZX-91 newsletter. Created mostly on a ZX81 (Scribus was used for page layout and PDF creation). All text and images were done on a ZX81 (using sz81 emulator).
| Title | Description | Computers |
|---|---|---|
| Another Look at Zeditor | Although ZX-91 used Word Sinc II, the program has issues on emulators. I needed a word processor that could same files on modern systems. I realised that I have reviewed such a word processor in issue 7, called Zeditor. Looking at my original article, I did not test out Zeditor very well, especially doing more […] | Sinclair ZX81, Timex/Sinclair 1000 |
| Debugging Assembly with Hot Z-II | I recently started working on some assembly code that I had not touched in a long time. The assembled code (.p file) was working. I relooked at the code, re-assembled it and it failed to work. A cursory look at the code does not show the problem. As fast and small as assembly is, it […] | Sinclair ZX81, Timex/Sinclair 1000 |
| Development on the ZX81 | These days most program development on the ZX81 happens using tools on other operating systems and running the program on the ZX81. Basic tools like zxtext2p or the C compiler Z88DK, or a cross assembler like PASMO are examples. It is still possible to do development only on the ZX81. With Basic, there is the […] | Sinclair ZX81, Timex/Sinclair 1000 |
| Memocalc | I have mentioned MemoCalc before in ZXzine, but with the focus of this newsletter being applications that are still usable today, I needed to bring up MemoCalc. In the early days of computers, word processors, spreadsheets and databases were the three main applications that all computers had. Sinclair released Vu-Calc from PSION. It was a […] | Sinclair ZX81, Timex/Sinclair 1000 |
| Music on the ZX81 | The default music device on the ZK81 is the Zon X-81. It was an add-on that came with an AY chhip and built-in speaker. Many emulators and ZXpand emulate the Zon X-81. To create music, Andy Rea has created ZXbeta, a music tracker program for the ZX81. It can be used to create your own […] | Sinclair ZX81, Timex/Sinclair 1000 |
| What is ZX26? | In 1991, Andre Baune of Quebec, Canada, published a newsletter called “ZX-91: 10 Years Later.” It was a newsletter for the ZX81, created solely on the ZX81, with 16k and a TS 2040 printer. Andre used Word Sinc Il as the wordprocessor and it was able to do lower case letters on the TS 2040 […] | Sinclair ZX81, Timex/Sinclair 1000 |
| ZX81 and Computation | Another use for the ZX81 is computation, or in other words, number crunching. Despite being a slower computer even when it was new, the ZX81 is still far faster and more capable than a calculator. Given the ease of use of BASIC, the ZX81 is a fairly accessible computer for uniting mathematical code. Given its […] | Sinclair ZX81, Timex/Sinclair 1000 |
