Re: ZX81 Toddy Forth-79

Re: ZX81 Toddy Forth-79 - New fix release

Hello guys! After a long time away and motivated by this video on YouTube , I turned my attention to the TF79 and ended up discovering issues in the behavior of the words INKEY and WAIT, which motivated a new release. I also took the opportunity to correct what I now recognize was a bad decision: th...

Re: Frontend for ZXpand+ with pictures on the right side?

Then select the BMP file and hit the NEWLINE to show the image. Note that the screenshot generated by the ...

Re: UDG chars for ZX-Nibbler

Love it! Did you speed it up too, or am I imagining it? You are imaginning it, the only changes I made to the program were on lines 6070 and 9651, changing the characters [-], [>>] and [<<] for [:] and [**] respectively. Weirdly it looks totally different on a Raspberry Pi. What is the emulator? It...

Re: Micro Sistemas Go program

how to I manage to start the program "Go" from https://zx81.eu5.org/msprog.htm ? The program is missing the byte 80h that marks the beginning of the variables area. Some emulators ignore this, but not EO. This failure was probably caused by the xtender emulator used in the conversion of programs al...
