Sinclair ZX80 / ZX81 / Z88 Forums

I used the Makefile (without .z81) without any additional flags. Normal and hires modes work also on an old 32 bit machine. So for now it is a mystery... I also compiled it on Ubuntu 10.04 LTS (IA32) and I get the same run-time misbehavior with sz81 as on Linux, i.e. the hi-res screens are blank. I...

Yes, and on Raspberry Pi, but I havn't tried it with WRX16. Your probably works too for normal use but not now with WRX16 on Raspberry Pi. I read about WRX1K, will that also be supported?

Does it compile? Yes, but I have the same problem as in my edited post above i.e. in sz81 it was just a blank screen and in xz81 there was random noise. (One idea of what might be wrong: I know that the gcc on RasPi has different defaults compared to other compilers when it comes to char so you sho...

In the meantime I tested if my patches also work with Thunor's sz81 and yes :) see attachment. I applied the patches using patch < file.patch to sz81-2.1.7-source.tar.gz from http://sz81.sourceforge.net/#downloads but after that make and make -f Makefile.z81 wouldn't compile to executable files. I ...

I found the following at http://www.zx81.de/english/zx80_e.htm: Take the zx80.rom file and burn it into a 2532 EPROM (not 2732!). Replace the ZX81 ROM with this 2532 and disable the NMI signal from ZX81 ULA by cutting the connection from ULA to Z80A CPU. Maybe one could hack the ZX80 ROM for the ZX8...

On the ZX81 I do But I get syntax-error on the last line after 2. I think this should work because this works in MATLAB. Still, it's good that it works for strings.

The ZX81-script with VAL now works! I see you can read and set environment variables but only if they start with ZX and when you set they are not set directly but stored in a file zx81.env which one can run with source. This makes it difficult to use ZX81-scripts as CGI-scripts without using a wrapp...

I tested shebang with this program: #!../zce # set path to zce and execution bit 10 if not len a$>0 then goto 30 20 print a$;"=";val a$ 30 rem # in bash, use "echo $?" to observe report code It did work with expressions that don't contain functions or ** (power). I think there is some bug in the tok...

I tried to complile xterm with Sixel-graphics and run zce in it, and succeeded. First, I couldn't run configure, but after sudo apt-get install libxaw7-dev it worked. I got this error when I run make: In file included from ./input.c:90:0: ./xtermcap.h:64:20: fatal error: curses.h: No such file or di...

I don't have any option with Sixel when I Ctrl+left, right or middle click in xterm in Ubuntu Linux 10.04 LTS or Ubuntu 12.04 LTS. I think Sixel-graphics was introduced in 2013. The README-file is not changed about RUN and GOTO. I think all ZX81-commands that works in programs should exist in upper ...
