Just look at list of files. There is ZXzine3.pdf and ZXzine3.zip (which contains the programs and source code).

For functions and procedures, you have to use GOSUB. If you have function - func(y) 10 let x = func(10) Assume the code for the function starts at line 1000, this is how you would run it: let y = 10 gosub 1000 print x you would just make sure that the function would set the results into variable X, ...

> I'm not at my ZX81 so I can't check the RAM but does it come with 1K and is it shielded? The ZX81 came with 1K and the T/S 1000 came with 2K. Once the 16K ram pack was installed, then they both had just 16K (the internal memory was switched off). My first ZX81 died with a keyboard problem. It repl...

The ZX81 hit the US first, but it was sold via mail order only in Oct. 1982. The T/S 1000 hit the market in July 1982 and was competing against the Vic-20, TRS-80 Coco, and Atari 400/800. Yes a bunch of the market was for gaming (esp. kids). I think one of the major issues was that Timex did not mar...

I just happened to discover that the Internet Archive has issues of Zxir Qlive Alive (Sir Clive Alive), the newsletter for the North American Timex/Sinclair User Group.

For short type-in games, a number of past issues of Sinclair User are available from the Internet Archive. There should be some in the early issues.

Look for ZXine2.pdf and ZXzine2.zip. The zip file contains all of the related files from the issue.

I just downloaded and tested sz81-2.2. Great job getting the WRX hi-res working. That was the biggest lacking feature of sz81. sz81 is my favorite ZX81 emulator. It is native to Linux and it has a mouse driven GUI front end controlling it, making it very easy to use. I have EightyOne running under W...

As I've been doing work / tinkering with the ZX81, I've always like to write up what I have been doing. With no outlet for this writing, I've decided to create ZXzine, an e-zine for the ZX81. I also work in the QL, and I've created an e-zine for the QL called SMSQzine. Both are free (creative common...
