Re: ZX81 emulator for iOS

I have some feature requests for iOS ZX81 app v1.13.3: I have a switch on my ZX81 that inverts the colors, i.e. white becomes black, and vice versa. It would be good to have a similar switch near the screen, because I like dark mode and did so 43 years ago. It also flips colors of the frame. I guess...

Re: New release of EightyOne available

I think it would be a good thing if EightyOne also was a package on Chocolatey. It would simplify updates and increase the number of users on Windows. They already have e.g. a VIC20 and C64 emulator, WinVice: https://community.chocolatey.org/packages/winvice-nightly They also have a PC emulator, DOS...

You can put your ZX81 programs online for free on GitHub.io; example Aritm - mental calculation

You can run my "Aritm - mental calculation" online on https://mobluse.github.io/zx81js/zx81kb.html?track=Aritm.tzx.zip. Aritm has also been published on this site earlier https://www.sinclairzxworld.com/viewtopic.php?f=6&t=4694. The site where it's linked from is on https://mobluse.github.io/zx81js/...

Re: Aritm for ZX81

Aritm is short for "aritmetik" i.e. arithmetic in English. Aritm for ZX81 works better if you use the improved ROMs such as "X2": https://sinclairzxworld.com/viewtopic.php?p=40327#p40327 When I ran Aritm for MS-DOS in C (1992) I also had flashbacks to classroom competitions in the 70s which I was no...

Re: CONT or CONTINUE in BASIC programs

CONT in a programme is like a REM I don't agree to that because CONT is like GOTO last executed line unless STOP because then GOTO last executed line +1. In this program you RUN and then press CONT and then SPACE/BREAK key, then CONT again and BREAK etc. You can also try RUN 75 and then press CONT ...

CONT or CONTINUE in BASIC programs

Is there any use for CONT (or CONTINUE for ZX Spectrum) inside a BASIC program? CONT inside programs works different in e.g. ZX81/ZX Spectrum vs VIC20/C64. I know that CONT is useful on the command line. CONT Suppose p/q was the last report with a non-zero. Then CONT has the effect GOTO q if p <> 9,...

Re: ZX81 emulator "command-line edition"

Now this entire site has disappeared:
"This site can’t be reached
rullf2.xs4all.nl’s server IP address could not be found."

I think it better to place free open source software (FOSS) also on GitHub (or maybe GitLab) so that it doesn't disappear.
