Basic beyond 16K

I'm trying to write a Basic program that will be more than 16K. I've been testing this out with three emulators, sz81, Zesarux, and JSZeddy. Each emulator allows for memory over 16K. I've read the Memotech 32K and 64K manuals and follow their steps: - Set emulators to more than 16K - Start emulators...

Re: AZMIC ROM

Pokemon, There was no full cursor, just some odd looking graphics junk.

Olofsen, Thanks for the pointer to z81. I'll have to give that a try.

The ASZMIC ROM sounds interesting and might be worth tinkering with.

Re: AZMIC ROM

Now the question is: which emulators does the ASZMIC ROM actually work on. I tried it with sz81 by renaming the .bin file to zx81.rom and put it into the data directory for sz81. That did not work. There was a funny cursor display. Anybody tried it with other emulators?

Astronomy Programs

Back in the day, one the books that I had to get was " astro.zip More Uses for the Timex Sinclair 1000: Astronomy", by Eric Burgess and H. J. Burgess. This book was related to the book "Celestial Basic" which had programs for the Apple II. I don't think I typed any of the programs in, but recently I...

Re: Other Compilers

It's been over a week with no replies, so I can safely say that no one on the Board can answer my questions. I did some research on the different ZX81 compiler and here is what I found out: The first compiler advertized was ZX Autocoder, produced by Control Technology of Hyde, Cheshire, UK, in the A...

Other Compilers

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 ...

Re: ZX80/81/Spectrum emulator for Unix

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...

Re: ZX-LSYS LINDENMAYER SYSTEMS

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...

Prime Numbers

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...

Re: ZX81 Sofware Repository

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...
