This later version also supports the ZX80:

I can create a .wav file but it cannot be loaded into a real TS1000 or a real ZX81. All other .wav files that were created by EightyOne (about 8 of them) work with no problem. When I convert this particular one (the one for madn.bas) using an old 1999 tool, ZXC.EXE (which created a .RAW and then Au...

Do you mean you can't create create a .wav file, or you can but it won't load into a real ZX81?

It was quite badly corrupted but because it was based on the ROM's LOAD code it was relatively easy to repair the corruption.

On top of that earlier cassette I have come across a different one where the label suggests that it contains compiler for MC or GMSave. Link is below but there's a lot of distortion recorded into the tape - I don't know if you'd get anything useful from it. I've had a look and it is quite badly cor...

he has suggested he might have got it from Toni Baker's book on Machine Code but he'd not sure. I'm going to send him a link to this thread so he might have some more info.

Any info on who made GMSave would be very useful to know, e.g. was it a purchased program or typed in from a magazine. I think from what...

The Fast Loader is remarkably similar to the one here on my website . A comparision of the machine code shows it is identical except for the displayed date and name of the cassette routine. So it appears to be an earlier version. I don't know the history of the routine so if anyone does then I'd be ...

You can format the line exactly as shown, e.g. say you wanted to print a "A" at row 8 column 5 you would use: POKE 8*33+5+1+PEEK(16396)+PEEK(16397)*256,38 or if you could evaluate the maths yourself and use: POKE 270+PEEK(16396)+PEEK(16397)*256,38 or to make it clearer which character you are printi...

Simon from Cronosoft recently posted the following on Facebook: KongRelease1.png Along with this photo: KongRelease2.png This new version of th...
