I managed to make it work a bit but I don't happen to see my assembled code in memory and I can't seem to use the supposed D commands?!?!
I now have a source file and an .obj on an atr image.
The ASM command produces no error and a nice onscreen listing.
Note: I typed "ASM" alone, hoping that this assembles to memory!
Now how can I call my code at the specified location and how can I peek/poke the RAM with the monitor?
This DDT thingy lists me a lot of BRK instrcution at my code location?!?
