Sinclair ZX80 / ZX81 / Z88 Forums

I've just compiled the source 0.6 SN March 31st. The configure detects the presence of the ssl library and adds it to the ld flags, but an ldd of the executable does not show the library... With spiro and --realvideo the options are all set as you described, but the image is not stable in the x dire...

Hi Cesar, yes I did (version of 27 March)- it is a great project! I've tried the examples I mentioned (with and without --realvideo) but the video was not ok; I may have missed another option? I'm getting closer to understanding how xz81 works so my hope was that the patches may be of some help.

Attached is an attempt to patch xz81 (by Marks) for hires, so that it seems to work at least for two examples (JUL-FFP.P and SPIRO.P). The first change to z80.c relaxes the timing of the bytes to be plotted, the second gets them using IR, the third one avoids early fake syncs). The change to common....

Yes, environment variables cannot be set directly. The report code may perhaps be useful, which is the available as "$?" in bash: 10 let theanswer = 81 20 poke 16384, theanswer-1 30 rem not run Using ZX81 scripts (with PHP) is an interesting idea. I've added a first example on the project web page. ...

The behavior of the automatic listings should now be more similar, but not yet identical to that of the ZX81 (using variable "s-top"). The tokenizer only worked when compiling a program. So the argument passed via A$ was never tokenized. In addition, strings were not tokenized, because in an ASCII s...

Yes, INPUT reads from stdin. And the question is how often to output the screen to the terminal. I chose to output it before an INPUT (unless in pure command-line mode rerouting 0). The "REM $S" command may be used here to output the screen. So the following code would work: 10 PRINT "ZCE" 20 PLOT 3...

Compiling XTerm could be straightforward: Download from http://invisible-island.net/xterm/#download Just ./configure --enable-sixel-graphics ; make Run the created executable with the options as showed before. I agree that the available commands and the documentation need some attention. Shebang is ...

The command to start XTerm is correct. With ctrl-3rd mouse button one gets the VT options, and option sixelScrolling should be there if it is compiled in. Indeed - for now I added RUN and GOTO in uppercase. When using PRINT at the command prompt, it will LPRINT to stdout. "LPRINT LEN STR$ 1234" on t...

This emulator: http://rullf2.xs4all.nl/sg/zx81ce.html is a "command-line" edition, which is not suitable for playing action games, but it is capable of reading BASIC files in ASCII, and producing output in ASCII or in Sixel graphics. The latter can be viewed using newer XTerms and classical DECterms...
