Adding a border with IrfanView was just to demonstrate that the full 256x192 screen was properly cropped and nothing drawn was lost (and as the default "add a border" setting is 15 pixels on each side the resultant image will be 286x222). For the images uploaded to the Wiki I would not suggest cropp...

The manuals for DASM and DEMON in PDF format.

P.S. Does any one want me to upload a big PDF or two JPGs of the MC6809 Instruction Set Summary?

I have managed to create a CAS file, but I am unable to test it properly so it may not be perfect. If you can create a ROM from it, you can test DEMON by typing EXEC &HC000.

Lionel, I am confused, when cropping IrfanView does not impose an extra border that overrides the image. The crop mark image I included in my attachment shows the crop lines before cropping, after cropping the resultant image includes what is underneath those crop lines, not the crop lines, not a bl...

How do you create a cartridge ROM dump? Is it a case of CSAVEM "DASMROM", x, y, 0 and if so what are the values of x and y?

This is obvious in No 4 & 5: top & right lines lacking. This obviously results from the "frame" line bordering the picture. It would take at least 258x194 to get a complete picture, as I already suspected. Yet, for a strange reason I stated yesterday, but am still unable to explain, 258x193 (offset...
