Hi Peter,
You need to load the MCW first, that has a memory bar to see how far it is filled.
You can not extract the cartridge-content as MCW, only as binary dump.
Your content as MCW-file can be found here:
viewtopic.php?f=19&t=1304See screenshot of my BETA workbook.
240k used, programmer disconnected ZzZzZz..
The latest stable firmware can be found here:
viewtopic.php?f=17&t=1585MCW file is in the advanged user download.
Now a days I use altirra as emulator.
It's a very powerful emulator that supports MyIDE-][ hardware.
(you need the binary dump and use it as firmware image)
Grtz,
Sijmen.
