Re: Drop the PRINT instruction on ZX80

From what I remember seeing SHREB doing, it's usually formulated like: IF USR MC-ADDR THEN REM <stuff to parse or execute by MC routine> My guess is that the MC function then returns 0, meaning the THEN part never gets executed (which in this case it wouldn't, being a REM , but other tokens could be...

Re: Drop the PRINT instruction on ZX80

The command PRINT USR(30000) will come back with 30000. But I want to surpress the printing. How can I drop the PRINT instruction from the stack? Is there good textbook for MC programming on ZX80?

Re: Where can I find "true" ZX81 fonts

I am working on a project and I need a windows font with the all the graphic characters. The ones I find do have the alphanumeric characters and their inverse but no graphic characters.

macOS Quicklook plugin for ZX81 files

A while back I mentioned I was working on a Quicklook generator for ZX files; I've finally gotten around to finishing and releasing it. :D

You'll find it here on GitHub: https://github.com/sebastienboisvert/ZX81QuickLook.

Enjoy!

Odd LIST bug/behaviour

New Sinclair BBS online

New BBS at http://telnetbbsguide.com/bbs/sinclair-retro-bbs/

The page has a built-in terminal emulator to connect using your browser, but for kicks I tried connecting with ZX-TERM*80 in EightyOne and it works! (though I couldn't get the graphics mode to ASCII only)
