Re: Steven L Reid's BASIC programs

Thanks for the feedback Steve, I'll have a look at those improvements that you mentioned. The POKE is opening the bottom two lines of the screen so that they're writable during the program execution by the interpreter. I intend to put a high score and score there (and maybe use the very bottom line...

Re: Steven L Reid's BASIC programs

Worked great Shaun. You must have to keep the character list up while reducing for memory. It takes me a bit to read through the listing without the numbers. Curious, what does the poke at line 10 do? Also, I think that VAL "16418" is 8 byes, where the number only would be 7. Not sure you saved anyt...

Re: Steven L Reid's BASIC programs

Hi, Thanks for the great programs. I've been working through Fly Wheel and have so far trimmed it to ~7500 bytes without losing any speed by condensing some of the PRINT routines to 1 line and some other techniques. I'm also going to change the keys to 5 and 8 as the . is too close to the 'break' k...

Re: Long scrolly on an unexpanded machine

Pretty cool. Runs well too. You can get a few more bytes (15 by my count) out of it. I dropped unneeded parens and removed +NOT PI on line 4. I found you don't need the SGN PI*() in lines 7 and 8. Flipping lines 5 and 6 lets you drop a space from A$ which gives you another byte. Allows you to add 16...

Re: JSZeddy

I am trying to diagnose why the jtyone keyboard input on Macs is not working (I assume you are on a Mac, my PC keyboard works fine). Unfortunately I have no access to a Mac - if anyone has one and is willing to run the emulator and capture the console output resulting from a few keypresses I would ...

Re: JSZeddy

I remember why I didn't use JtyOne, I couldn't get it to read the keyboard. So, good for iPad, but not so good for a laptop.

Re: JSZeddy

Great site you have and good to hear that it works! Let me know which programs don't work, especially if these work on JSZeddy's website, because there may be some bug fixes. Alternatively, you may wish to check out http://www.zx81stuff.org.uk/zx81/jtyone.html Will do. I did see jtyone was now Java...

Re: JSZeddy

Finally got around to testing this out on my site and so far so good. I was able to replace the old Java JtyOne emulator with JSZeddy and it works pretty good. Here is an example . I'm still hacking a bit at the overall layout and I can't decide if I want to include the keyboard or not. There are al...

Re: JSZeddy

Woah! A working ZX81 javascript emulator! Where have you been all my life? So far it runs all the standard basic programs I've thrown at it. I'd love to replace the Java emulator on my web site as it is getting harder and harder to keep working and doesn't work on tablets. :( Were you planning to al...
