Perfect - Works a treat. Thank-you so much for your time here, really appreciated. Great, good to hear! Yes, Paul’s (Fruitcake) work on maintaining and improving EightyOne is much appreciated. As is his other work on Sinclair ZX80, ZX81 and ZX Spectrum projects. So a very grateful thank you from me...

Has saving/loading memory blocks been fixed? I know it was borked in some versions as I needed it to load/save certain memory blocks to use as ROM files and ended up going back to earlier versions to get it to work. I'm not aware of there being a problem with this functionality. Could you list the ...

Well it’s the start of a new month and I have a very interesting discovery to report. As you will know, Sinclair sold the ZX81 ROM as an upgrade to the ZX80 to enhance the computer’s ability from integer only maths to floating point maths.

Version 1.34 of EightyOne has just been released. The changes are: Breakpoints can now be disabled. Breakpoints can now have a hit count assigned to them and will only trigger after the breakpoint condition is met that number of times. ZX80 and ZX81 BASIC listings can now also be saved out in ZxToke...
