XavSnap, Can VB81 disassemble 'Organizers' initial option 'RECORD LAY OUT', followed by a new mode called 'DATA-FIELDS', to see how clever this mixed language program's code operates, thanks?

Hi,
The following link is a combination of assembly and ZX81 BASIC program called 'Organizer' with no data.
VB81 does not allow normal cursor movement, which is the heart of the program.
Please confirm and if possible make cursor move w/o hitting 'SHIFT', etc.

Hi,
There are ZX81 emulators claiming to 'LOAD' a *REAL* tape.

Is there some way to get 'Audio In' fully functional on this emulator?
Please post where to find 'Audio IN' and 'Audio OUT' in eightyOne SRC?
THX!

When generating standard ZX81 type characters SHREB expects to find the character patterns at $1E00, which are are no longer there because of the ZXPand overlay ROM. Pseudo-hi-res programs also have a similar problem. Try loading the program with the /...

Here it is with SHREB version 3. I haven't actually tried to figure out how the use the program, but the screen shot shows that SHREB version 3 is working. Regards; Greg Greg, The SHREB version 3 appears to handle Tom's SE graphics, but not regular text. If you know the subtlety between 2 and 3, pl...

mrtinb,
ZXpand did the job, thx!
Now, the attached >16K file ZXpand SAVEd, will not LOAD via EO tape, only ZXpand CAT.
What's the trick to get EO tape/wav to LOAD it, as well
