Sinclair ZX80 / ZX81 / Z88 Forums

After tinkering with MCoder II, I started thinking about other ZX81 Basic Compilers. I have found the .P file for the Silversoft ZXCompile, but is no manual. I've tried it out but I have not got it to work. I've seen other compilers advertised, like ZX Autocoder (by Control Technology), ZXpress (by ...

Getting support for WRX would be nice. Right now I am using sz81 and it does not have support for WRX and there is no on-going development, so I can't try out any of the new programs. For the Menu, I found that the number of keystrokes was fairly high to load a .P file. With sz81, once I navigate to...

Another good use of the ZX81 for computation. Looking L-systems I found that they have something in common with cellular automata, they both have a grammer. The rewriting part is interesting and I've never encounted that idea (except for Sendmail rules which have a form of rewriting). It think it wo...

Many years ago I ran across a person that said that he created an algorithm that would quickly determine if a number is a prime. The algorithm was odd and I did not trust it. Recently I remembered it and wrote a short paper on the algorithm, including the rather confusing explanation of the algorith...

Moggy, "it looks plus all the magazines You could ever want (including Sync Timex/Sinclair user) are stored on the WoS site" It looks that way, but by looking into the directories, they are short on issues of the magazines. I have found the Internet Archive useful in many other areas, esp. census fo...

Over 1400 titles? That's going to take a while to go through. I'm finding more and more in the Internet Archive. They also have archived copies of Your Computer, ZX Monthy, Sinclair User, Sync, and other early 80's computer magazines. I was going to scan my copies of Sync, but they are all there on ...

I've been looking at the ZX81 from the point of using it for comutation work. I did some Google searches looking to see if I could find any reference to the ZX81 in academic publications. I found a number and I thought that readers on this board might find them interesting. Only a few of the article...

Siggi, Thanks for pointing out the issue with the 16-bit variables. I've edited the paper to indicate this and changed the example to one what would not go over 64K. I've also added links in the website to the source code examples in the paper. I have not tried the different pokes to modify MCODER2,...

After tinkering around with MCODER2, I decided to write up a short tutorial on using MCODER2, It is a 7 page PDF document that goes over the steps in using MCODER2, and includes a little cheatsheet with the different USR calls for MCODER2. Now, I'm not an expert at MCODER2, but I like to document wh...

"Compute!" did cover the T/S 1000 occasionally, but the two main Sinclair magazines in the US were "Sync" and "Timex/Sinclair User." I have a number of issues of both (maybe all of T/S User) and am in the process of scanning them in for archival purposes. I have done three issues of both magazines. ...
