I have the ROM dump for this in P file format if you're interested? It can be loaded to the appropriate memory address in a ZXpand, should you have one, and used in the same way as the real thing with the bonus of SD card load and saving instead of tape.

Good idea, Moggy.
It's easier to use on a SD ZX81...

The raw ROM & manual are available here: http://zx81.ordi5.free.fr/memotech/MT_Z80Assembler/
JPG : http://www.zx81stuff.org.uk/zx81/hardware/Z80Assembler

Is there a MT11 like the Memocalc or the Memotext cards ? (without the autostart button)

Thanks for this Xavier as it's handy to have it all in one place.

The ROM as I remember needs to loaded to 12288 in the ZXpand and called by 16258 after following the instructions in the manual.
Mrtinb has made some improvements to how this is used that are very useful.

Information for this can be found here....

Read all three pages as he has made updates at the end and these are the ones to use.

Hi,
I tried to get the wiring diagram on the Moggy's pictures...

But i can't read components values, hidden tracks and the setup jumpers links.

Have fun.
